The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), intends to negotiate a sole source contract with Kanomax FMT for the procurement of a focused aerosol deposition system. This system is required for generating particles from ultrapure water and collecting them on substrates for offline analysis, with specific technical specifications including a collection efficiency of approximately 100% for particles as small as 5 nm. The acquisition is critical for NIST's Material Measurement Laboratory, Chemical Sciences Division, and is based on market research indicating that Kanomax FMT is the sole manufacturer capable of meeting these requirements. Interested parties must submit their capabilities in writing by 11:00 a.m. EST on December 27, 2024, to Jenna Bortner at jenna.bortner@nist.gov and Donald Collie at donald.collie@nist.gov.
