The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is conducting market research to identify potential sources for a Cavity Ringdown Gas Analyzer designed for trace moisture analysis in semiconductor manufacturing environments. The primary objective is to acquire a gas analyzer that can accurately quantify water vapor partial pressure in vacuum lines, with a sensitivity of less than 1 part per billion, to support advanced process control and modeling in high-volume manufacturing. This equipment is critical for ensuring the purity of chemicals used in semiconductor processes, as moisture can lead to impurities and byproducts that affect product quality. Interested vendors are encouraged to submit their capabilities and relevant product information to the primary contact, Elizabeth Timberlake, at elizabeth.timberlake@nist.gov, by the specified deadline, as this notice is for market research purposes and does not constitute a commitment to award a contract.
