New clarification added: Q10. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot #5  HPLC with DAD and FLD detectors, Section C - Technical Requirements, Line 25 (Dosing range 0.1-100 µl. Optionally, dosing range extensions up to 2000 µl should be available), could you kindly reduce this parameter to 1500 μL, as in typical HPLC applications the sample injection volume does not exceed 10–50 μL and a volume of 2000 μL is rarely used? Maintaining the current requirement may limit the number of qualifying manufacturers and thereby restrict fair competition.A10. The request to revise the optional maximum injection volume from 2000 µL to 1500 µL has been reviewed.It is acknowledged that in standard HPLC analytical practice, injection volumes typically remain significantly below 100 µL, and extended volumes are rarely utilized. It is further recognized that maintaining unnecessarily high optional limits may reduce the number of technically compliant bidders.In order to promote fair competition while maintaining the functional integrity and flexibility of the system, the requested change is considered acceptable.Requirement will be revised :Dosing range 0.1–100 µL. Optionally, dosing range extensions up to 1000 µL should be available.

New clarification added: Q7. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot#4 HPLC with FLD and RID detectors, Section C - Technical Requirements, Line 25 (Dosing range 0.1-100 µl. Optionally, dosing range extensions up to 2000 µl should be available), could you kindly reduce HPLC injection volume from 2000 μL to 1800 μL, as the current requirement does not reflect typical usage and may unnecessarily limit competition among potential bidders?A7. The request to revise the optional maximum injection volume from 2000 µL to 1800 µL has been reviewed.It is acknowledged that in standard HPLC analytical practice, injection volumes typically remain significantly below 100 µL, and extended volumes are rarely utilized. It is further recognized that maintaining unnecessarily high optional limits may reduce the number of technically compliant bidders.In order to promote fair competition while maintaining the functional integrity and flexibility of the system, the requested change is considered acceptable.Requirement will be revised :Dosing range 0.1–100 µL. Optionally, dosing range extensions up to 1000 µL should be available.

New clarification added: Q5. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot#2, Section B - Technical specifications, Line 23 (Net weight shall not exceed 350 kg, External dimensions shall be within (LxWxH) 1500x1500x1900) mm), this does not correspond with typical emission test chamber configurations, as a 225-liter chamber integrated within a climate cabinet generally exceeds 500 kg. Please reconsider the weight limit of 350 kg, given that compliant systems typically exceed this weight.A5. In order to ensure fair competition while maintaining the functional and operational requirements of the system, the requested revision is considered acceptable.Revised Requirement:Net weight shall not exceed 500 kg. External dimensions shall be within (L×W×H) 1500 × 1500 × 1900 mm.

New amendment added #1: To extend the bid submission timeline until 13 April, 2026. 

New clarification added: Q21. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot #3  Gas Analyzer, multicomponent, Section B - Technical Specifications, Line 7 (Limits of basic and relative error ±10%), could you kindly revise the relative error requirement from ±10% to ±25%, as this aligns with industry standards for the intended applications and avoids unnecessary cost and complexity?A21. The request to revise the allowable error to ±25% has been carefully considered.Please be advised that the specified requirement of ±10% has been established to ensure sufficient accuracy, reliability, and comparability of measurement results, particularly for environmental and sanitary-hygienic air monitoring applications. This level of precision is essential when measuring low concentrations of pollutants and supporting decisions related to public health and environmental protection.While higher error margins may be acceptable for indicative or screening instruments, they are not suitable for the intended use under this procurement. Increasing the allowable error to ±25% would significantly reduce data quality and limit the applicability of the results.Accordingly, the request cannot be accepted, and the requirement remains unchanged.

New clarification added: Q19. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot #3  Gas Analyzer, multicomponent, Section C - Power supply, Line 21 ("Mounting kit - 1 pc.Calibration nozzle 1 pc."), given that the device is portable, a mounting kit is not needed and the calibration can be performed without a special nozzle, so could you kindly remove this requirement?A19. The request to delete the mounting kit and calibration nozzle has been reviewed.It is clarified that, although the device is specified as portable, the inclusion of a mounting kit remains required to ensure flexible and secure positioning of the analyzer in various operational scenarios, including temporary or semi-fixed monitoring setups, where stability and proper placement are necessary for reliable measurements.Furthermore, the requirement for a calibration nozzle (or equivalent) is intended to ensure controlled and accurate calibration procedures, in line with good measurement practice.However, it is clarified that:If the offered analyzer utilizes a different calibration method or interface than a standard calibration nozzle, such solution may be accepted,Provided that the Bidder submits official manufacturer confirmation that the proposed calibration approach ensures proper, accurate, and reproducible calibration of the device, andThe proposed solution is fully compatible with the analyzer and suitable for its intended use.

New clarification added: Q17. Could you please extend the tender deadline to allow enough time to prepare all the required bidding documents?A17. The deadline for tender submission has been extended to April 13, 2026. However, the deadline for clarifications remains unchanged. 

New clarification added: Q16. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot #3  Gas Analyzer, multicomponent, Section B - Technical Specifications, Line 4 (Acceptable measurement methods used by the device: electrochemical, NDIR, UV fluorescence, photoionization (PID) depending on the component being measured), please kindly confirm if it is acceptable to use sensors such as semiconductor, thermocatalytic, optical?A16. The request to allow additional sensor technologies (semiconductor, thermocatalytic, optical) has been carefully reviewed.It is clarified that the specified measurement methods (electrochemical, NDIR, UV fluorescence, PID) are intentionally defined to ensure that the offered system provides high accuracy, selectivity, stability, and reliability, in line with internationally recognized practices and applicable EN standards referenced in the technical requirements.These methods correspond to established analytical and reference measurement principles widely used in environmental and regulatory monitoring. In contrast, the additionally proposed sensor technologies (such as semiconductor and thermocatalytic sensors) are generally applied in indicative or safety monitoring applications and do not provide the required level of analytical performance, selectivity, or long-term stability necessary for the intended use.Furthermore, it has been confirmed that the current requirement is fully supported by multiple internationally recognized manufacturers of reference-grade gas analyzers, and therefore does not restrict competition.

New clarification added: Q15. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot #3  Gas Analyzer, multicomponent, Section D - Components, spare parts, consumables, Line 23 ("Compliance with standards, such as EN 14626, EN 14211, EN 14625 (if applicable), availability of verification proceduresOperation manual, maintenance manual, manufacturer's passport, certificates of conformity and quality.), these standards describe the determination of gases by the following methods:EN 14625 --UV photometric.EN 14626-NDIREN 14211-Chemiluminescence. Could you please confirm if it is acceptable if the gases are detected using different types of sensors instead of the specified methods?A15. Referenced EN standards (EN 14625, EN 14626, EN 14211) define reference measurement methods for the determination of specific gases (e.g. UV photometric, NDIR, chemiluminescence), and are internationally recognized for ensuring accuracy, reliability, and comparability of results.In this context, the requirement for compliance with these standards shall be understood as follows:The offered analyzer shall be designed and validated in accordance with the referenced EN standards and their corresponding reference measurement principles.Use of alternative detection technologies is not precluded, however such technologies shall only be considered acceptable if the Bidder provides clear and verifiable evidence that the system achieves full equivalence with the reference methods defined in the respective EN standards.Such equivalence shall be demonstrated through:recognized third-party certification (e.g. TÜV, MCERTS, EN 15267 / QAL1), orofficial manufacturer validation documentation explicitly confirming compliance with the performance requirements of the relevant EN standards.Solutions based solely on general-purpose or low-cost sensor technologies, without such verification, will not be considered compliant.

New clarification added: Q14. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot #5  HPLC with DAD and FLD detectors, Section D - Detectors, Line 52 (Wavelength accuracy not more than ±2 nm), please kindly reduce this parameter to ±3 nm, as strict compliance may restrict competition; only a very small number of manufacturers are likely to meet the current requirement.A14. A wavelength accuracy of ±2 nm for a detectors is the de facto standard in high-performance liquid chromatography (HPLC) for the following reasons:Method Reproducibility: Chromatographic methods are developed based on strict parameters. A deviation of even 3 nm can prevent achieving identical results on a different instrument, as the substance's excitation/emission wavelengths will shift.Convergence of Results: In quantitative analysis, concentration calculations directly depend on the peak area. If the signal maximum is shifted due to detector error, the signal intensity drops, leading to calculation errors and incorrect analytical results.The ±2 nm requirement is not a restriction of competition, but a guarantee that the instrument will provide high reliability and transferability of analytical data between different laboratories.The technical specification requirement remains unchanged.

New clarification added: Q12. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot #5  HPLC with DAD and FLD detectors, Section D - Detectors, Line 45 (Wavelength reproducibility not more than ±0.1 nm), please kindly clarify whether wavelength reproducibility must be explicitly stated in the official documentation, or if compliance can be demonstrated through equivalent or related technical parameters, as these are commonly used in standard industry practice to characterize detector wavelength performance.A12.  Wavelength reproducibility of ±0.1 nm must either be explicitly stated in the documentation, or the bidder must provide manufacturer’s confirmation that the equipment meets this requirement through equivalent technical parameters.

New clarification added: Q11. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot #5  HPLC with DAD and FLD detectors, Section C - Technical Requirements, Line 30 (Cross-contamination level not more than 0.0025% with a caffeine solution), could you kindly reduce this parameter to 0.005%, as strict compliance may limit competition; only a very small number of manufacturers are likely to meet the current requirement?A11. Lot #5 includes a Diode-Array Detector (DAD) and a Fluorescence Detector (FLD), both of which possess extremely high sensitivity. When analyzing trace amounts of substances, a carry-over level of 0.005% will lead to the appearance of ghost peaks and distorted quantitative analysis results.Modern high-end HPLC systems provide a carry-over of less than 0.0025% as a standard feature, achieved through active needle wash technology and specialized sealing materials. Lowering these requirements would force the laboratory to perform additional checks to verify system cleanliness, leading to increased analysis time and costs.The technical specification requirement remains unchanged. 

New clarification added: Q9. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot#4 HPLC with FLD and RID detectors, Section D - Detectors, Line 51 (Wavelength accuracy not more than ±2 nm), could you kindly reduce this parameter to ±3 nm, as maintaining the current requirement may result in a reduction in the number of participants, allowing only a limited number of manufacturers to qualify and thereby restricting competition?A9. A wavelength accuracy of ±2 nm for a fluorescence detector is standard in high-performance liquid chromatography (HPLC) for the following reasons:Method Reproducibility: Chromatographic methods are developed based on strict parameters. A deviation of even 3 nm can prevent achieving identical results on a different instrument, as the substance's excitation/emission wavelengths will shift.Convergence of Results: In quantitative analysis, concentration calculations directly depend on the peak area. If the signal maximum is shifted due to detector error, the signal intensity drops, leading to calculation errors and incorrect analytical results.The ±2 nm requirement is not a restriction of competition, but a guarantee that the instrument will provide high reliability and transferability of analytical data between different laboratories.The technical specification requirement remains unchanged.

New clarification added: Q8. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot#4 HPLC with FLD and RID detectors, Section C - Technical Requirements, Line 30 (Cross-contamination level not more than 0.0025% with a caffeine solution), could you kindly reduce this parameter to 0.005%, as maintaining the current requirement may significantly reduce the number of participants, allowing only a limited number of manufacturers to qualify and thereby restricting competition?A8. Lot #4 includes a Fluorescence Detector (FLD), which possesses extremely high sensitivity (tens to hundreds of times higher than spectrophotometric detectors). When analyzing trace amounts of substances, a carry-over level of 0.005% will result in ghost peaks and distorted quantitative analysis results.The Refractive Index Detector (RID) is frequently used for analyzing sugars and polymers at high concentrations. When transitioning from concentrated to dilute samples, a 0.005% standard can cause significant contamination of subsequent analyses, necessitating additional rinse cycles and increasing laboratory downtime.Modern high-end HPLC systems provide a carry-over of less than 0.0025% as a standard feature, achieved through active needle wash technology and specialized sealing materials. Lowering these requirements would force the laboratory to perform additional checks to verify system cleanliness, leading to increased analysis time and costs.The technical specification requirement remains unchanged.

New clarification added: Q4. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot#2, Section B - Technical specifications, Line 5 (Сhamber volume of at least 250 liters or more) the tender requires a minimum chamber volume of 250 liters and compliance with ISO 16000-9 and EN 717-1. However, under these standards, commonly used chamber sizes are typically 225 liters (small test chamber), 1 m³, or 20 m³ and above. Please kindly confirm whether a 225-liter chamber would be acceptable in cases where compliance with EN 717-1 is required?A4. The request regarding chamber volume and applicable standards has been reviewed.The requirement for a minimum chamber volume of 250 liters is defined to ensure sufficient testing capacity and operational flexibility for the intended applications.At the same time, it is clarified that the requirement related to standards (ISO 16000-9, EN 717-1) refers to the suitability of the device for use in accordance with these standards, and not necessarily strict duplication of standard reference chamber sizes, provided that the system enables testing in line with the respective methodologies.Accordingly:A chamber volume of 225 liters does not meet the minimum requirement of 250 liters and therefore would be considered non-compliant with the stated specification.Where EN 717-1 is claimed, it is acknowledged that the standard is typically associated with 1 m³ chamber testing. In such cases, the system shall be suitable for operation in accordance with this standard.Compliance with at least one of the referenced standards remains acceptable, as previously clarified.

New clarification added: Q3. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Lot#2, Section B - Technical specifications, Line 22 (Device shall be suitable for use in compliance with at least the following standards: ISO 16000-9, EN 717-1) please clarify whether the bid should meet both of these standards simultaneously and whether standard EN717-1 is required for 1m3?A3. The wording “at least the following standards” indicates that the offered device shall be suitable for use in accordance with recognized international standards for emission testing, and that compliance with at least one of the listed standards is required. Accordingly, it is not mandatory for the system to comply simultaneously with both ISO 16000-9 and EN 717-1; compliance with either ISO 16000-9 or EN 717-1 is considered sufficient, provided that the offered system is fully suitable for the intended application and supported by appropriate manufacturer documentation.It is further clarified that EN 717-1 specifically relates to formaldehyde emission testing using a 1 m³ chamber. Therefore, where compliance with EN 717-1 is claimed, the offered system shall be suitable for operation in such configuration.All claims of compliance shall be supported by official manufacturer documentation.

New clarification added: Q2. As per Section_IV_Contract_forms - Annex III: Schedule of Requirements, Table 1 - the quantity of devices is indicated as two units each, whereas in Table 3 - for the same lots lists the quantity as one unit each. Please kindly clarify which table contains accurate information to properly prepare bidding documents.A2. The correct quantity of devices for Lots 4 and 5 is two units each. Tender document will be amended accordingly.

New clarification added: Q6. As per ITB_Section III Returnable Bidding Forms, Form D - Technical Bid Form, Delivery Requirements, UNOPS requirements, Delivery time for the goods ("Bidder shall make the goods available at FCA (Incoterms2020) preferably within 60 days available after receipt of confirmation from UNOPS to start the production processBidder shall deliver the goods to DPU (Incoterms2020) Tashkent, Uzbekistan within 90 days after Contract signature.Bidder shall perform the related services (installation, commissioning, training, etc.) within 120 days after goods’ arrival to Uzbekistan."), to deliver 15 chambers within 90 calendar days is highly demanding.Please confirm whether an extension of the delivery period would be acceptable, as fulfilling this quantity would typically take approximately 12–16 months, depending on the configuration.A6. Please be advised that the project schedule does not allow for any extensions to the delivery timeline.As per the requirements, the bidder must deliver the goods to Tashkent, Uzbekistan (DPU, Incoterms 2020), within 90 days of contract signature. Additionally, all related services—including installation, commissioning, and training—must be completed within 120 days of the goods' arrival in Uzbekistan. We consider this timeframe sufficient given the complexity of the technology.

New clarification added: Q1. Please extend the tender submission deadline, until 13 April 2026, to allow sufficient time to finalise all required documentation and ensure full compliance with the technical and administrative requirements of the tender.A1. The suggestion has been accepted. The deadline for tender submission has been extended to April 13, 2026. However, the deadline for clarifications remains unchanged.
