About this opportunity
The National Institute of Standards and Technology seeks quotations for one new X-ray diffractometer system, with quotations due September 3, 2026 at 9:00 AM EST and questions due August 17 at 9:00 AM EST. The procurement is unrestricted and eligible for Women-Owned Small Business participation. Amendment 2 provides government responses to vendor inquiries regarding cooling configuration and X-ray reflectivity absorber alternatives; NIST permits alternative approaches provided vendors submit supporting documentation and all proposals will be evaluated against stated specifications and requirements.
Place of performance is Gaithersburg, Maryland (Building 221, Room B153). The X-ray diffractometer must be a new, non-refurbished unit currently sold and supported by its manufacturer, capable of powder analysis in reflection or transmission mode, grazing incidence, and X-ray reflectivity measurements. Specific technical requirements include a 600W minimum X-ray tube source with copper anode and 40 kV accelerating potential, variable divergence slits, a detector with better than 400 eV energy resolution at room temperature, and 1D detector with 75-micron spatial resolution. The system must include a radiation safety enclosure, desktop PC with Windows 11, analysis software compatible with standard diffraction databases, and peripherals. Delivery must occur FOB Destination within 26 weeks of award; contractor must complete installation within 30 calendar days of delivery, provide one year of warranty covering all parts and labor, and deliver training within 30 calendar days of installation. NAICS code is 334516, Analytical Laboratory Instrument Manufacturing; PSC is 6640, Laboratory Equipment and Supplies. Evaluation criteria are Technical Capability, Past Performance (up to five relevant examples from the last three years), and Price. Award will be a single firm fixed-price purchase order without discussions based on initial quotations. Quoters must maintain active SAM.gov registration at submission and through contract award and final payment. The Contracting Officer is Sadaf Afkhami at Sadaf.Afkhami@nist.gov or (301) 975-3976.

AMENDMENT 2: The purpose of this Amendment is to provide Governemnt responses to vendor inquiries regarding the solicitation. Please see quesitons and responses below:
1. QUESTION: Cooling configuration (Specification 1.c)
The specification states that the X-ray tube source shall be cooled with an internal chiller and not require external water circulation. Would NIST consider an external closed-loop recirculating chiller, supplied as part of the complete system and requiring no facility water, provided it delivers equivalent cooling performance and system stability?
GOVERNMENT'S RESPONSE: Vendors are welcome to provide more than one quotation in response to the solicitation. All quotes will be evaluated in accordance with the requirements and evaluation criteria specified in the solicitation. Any alternative methods or solutions will be reviewed as part of the evaluation process to determine compliance with the applicable requirements. Please ensure that your proposal includes sufficient information and supporting documentation on how your approach meets or exceeds the stated specifications.
2. QUESTION: XRR absorbers (Specification 2.e)
The specification requires multiple absorbers, such as Cu films which can be stacked in 0.1 mm increments, for suppression of the direct beam during X-ray reflectivity measurements. Would NIST consider an equivalent configuration using selectable Cu absorbers of different thicknesses, provided the required attenuation range for XRR measurements is achieved?
GOVERNMENT'S RESPONSE: Vendors are welcome to provide more than one quotation in response to the solicitation. All quotes will be evaluated in accordance with the requirements and evaluation criteria specified in the solicitation. Any alternative methods or solutions will be reviewed as part of the evaluation process to determine compliance with the applicable requirements. Please ensure that your proposal includes sufficient information and supporting documentation on how your approach meets or exceeds the stated specifications.
3. QUESTION: Static stage for custom non-ambient cells (Specification 4.d)
The specification requests a static stage approximately 2 inches wide with screw holes for mounting custom non-ambient cells and states that the stage should be shaped as an L-bracket. Would a functionally equivalent, self-centering static mounting stage/adapter with appropriate provisions for securing custom non-ambient cells be acceptable if the mechanical design differs from an L-bracket?
GOVERNMENT'S RESPONSE: Vendors are welcome to provide more than one quotation in response to the solicitation. All quotes will be evaluated in accordance with the requirements and evaluation criteria specified in the solicitation. Any alternative methods or solutions will be reviewed as part of the evaluation process to determine compliance with the applicable requirements. Please ensure that your proposal includes sufficient information and supporting documentation on how your approach meets or exceeds the stated specifications.
4. QUESTION: Detector fluorescence rejection (Specification 3.a)
The specification requires detector energy resolution better than 400 eV at Cu Kα for fluorescence rejection. Our detector has an energy resolution of approximately 1800 eV but provides energy discrimination/filtering for fluorescence suppression. Would NIST consider this alternative detector approach, provided we can demonstrate effective fluorescence suppression for transition-metal-containing samples relevant to the intended applications?
GOVERNMENT'S RESPONSE: Vendors are welcome to provide more than one quotation in response to the solicitation. All quotes will be evaluated in accordance with the requirements and evaluation criteria specified in the solicitation. Any alternative methods or solutions will be reviewed as part of the evaluation process to determine compliance with the applicable requirements. Please ensure that your proposal includes sufficient information and supporting documentation on how your approach meets or exceeds the stated specifications.
Due date for quotations remains unchanged. All quotes are due no later than 9:00AM EST, on September 3, 2026.
