The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), intends to negotiate a sole source contract for the procurement of two nanoparticle nebulizers from Kanomax FMT. The required nebulizers must minimize interference from non-volatile particle precursors and feature a collection efficiency of approximately 100% for particles as small as 5 nm, among other technical specifications. These instruments are critical for NIST's Material Measurement Laboratory, particularly within the Chemical Sciences Division, as they facilitate precise aerosol deposition and particle generation for research purposes. Interested parties capable of meeting these specifications must submit their capabilities in writing by 1:00 p.m. EST on January 27, 2025, to the primary contacts, Jenna Bortner and Donald Collie, via their provided email addresses.
