The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), intends to issue a Sole Source Award to Tiger Optics LLC for a Cavity Ringdown Gas Analyzer designed to measure trace moisture in semiconductor manufacturing processes. The procurement requires a gas analyzer with specific technical specifications, including a detection limit of 1 µTorr or better, self-tuning laser capabilities, and electropolished stainless steel wetted surfaces, which are critical for enhancing metrology in the semiconductor supply chain. This initiative is part of NIST's efforts to improve process diagnostics for vapor phase deposition, and the notice invites responses from potential sources to provide relevant company details, product specifications, and compliance with the NAICS code 334516. Interested parties can reach out to Elizabeth Timberlake at elizabeth.timberlake@nist.gov or Donald Collie at donald.collie@nist.gov for further information, noting that this notice is for market research purposes only and does not guarantee a contract award.
