The National Institute of Standards and Technology (NIST) is conducting a Sources Sought Notice to identify suppliers capable of providing a Glow Discharge Mass Spectrometer (GDMS) for developing high-purity reference materials essential for accurate elemental measurements in semiconductor manufacturing. The GDMS must meet specific functional criteria, including the ability to analyze bulk solids without dissolution, cover a wide range of elements, and offer low detection limits. This initiative is part of NIST's efforts to enhance measurement standards through suitable commercial solutions, and interested vendors are encouraged to submit detailed information about their equipment and capabilities. For inquiries, vendors can contact Forest Crumpler at forest.crumpler@nist.gov.
