About this opportunity
The National Institute of Standards and Technology (NIST), under the Department of Commerce, has issued a Special Notice for the procurement of a High-Temperature Multi-Angle Light Scattering Detector (HT-MALS). This notice, posted on August 1, 2025, pertains to the Materials Measurement Laboratory's Materials Science and Engineering Division's requirement for specialized laboratory equipment. The acquisition falls under NAICS code 334516 for Analytical Laboratory Instrument Manufacturing and PSC code 6640 for Laboratory Equipment and Supplies. NIST intends to make a noncompetitive award to Waters Technologies Corporation for their DAWNa-UHT (NEON) detector. The notice establishes the agency's intent to sole-source this procurement under FAR 13.106-1(b) authority.
The procurement's primary objective is to enhance NIST's capability to determine absolute weight average molar mass measurements and polymer conformation plots for NIST standards and other polymers, while replacing legacy equipment that is over 12 years old and facing parts availability issues. The new detector must maintain compatibility with MSED's existing Wyatt HT-GPC instrument to ensure continuity with past measurements of Standard Reference Materials (SRMs). Based on NIST's market research, only Waters Technologies Corporation's DAWNa-UHT (NEON) detector meets the compatibility requirements, and Waters has confirmed it does not permit other sources to provide this detector in the United States. Contractors have until August 14, 2025, to respond to this notice, though the procurement is structured as a sole-source acquisition with no set-aside designation. The equipment will specifically improve detection capabilities for large macromolecules with complex branching distributions.
Notice text
The Materials Measurement Laboratory, Materials Science and Engineering Division (MSED) at the National Institute of Standards and Technology (NIST) requires a high temperature multi-angle light scattering detector to determine absolute weight average molar mass measurements and determination of polymer conformation plots for NIST standards and other appropriate polymers. The goal is to 1) improve the detection capability of large macromolecules with complex branching distributions (long and short chain) along with 2) replacing legacy equipment, where parts and service will soon become unavailable from the vendor due to the age of the instrument (12+ years). The new detector must be compatible with MML’s existing Wyatt HT-GPC instrument to ensure continuity with past measurements, particularly of Standard Reference Materials (SRMs) within the division. Compatibility with the existing Wyatt high-temperature Gel Permeation Chromatography instrument (HP-GPC) will allow synchronization with existing systems to ensure continuity with past measurements, particularly of Standard Reference Materials (SRMs) within the division.
Based on NIST’s recent market research, NIST has only identified one detector that is compatible with MSED’s existing HTC instrument: The DAWNâ-UHT (NEON), a product of Waters Technologies Corporation (Unique Entity ID: JFT8BGF7FKV6).
NIST has documentation from Waters Technology Corporation that it does not allow other sources to provide the required detector in the United States.
Based on the foregoing, the contracting officer intends to noncompetitively solicit, negotiate and award a purchase order to Waters Technology Corporation to purchase a DAWNâ-UHT (NEON). The authority for this action is FAR 13.106-1(b).
The North American Industry Classification System (NAICS) code for this acquisition is 334516.
