About this file
This is a Questions and Answers document for a federal solicitation (1333ND26QNB030133) issued by the National Institute of Standards and Technology (NIST) under the Department of Commerce for a Gas Chromatograph with Flame Ionization Detector.
The Q&A addresses the technical specifications and sampling requirements for the solicitation. The government will primarily sample bulk gases including nitrogen, air, helium, and argon at ultra-high purity levels of 99.999% or better. Air samples will contain approximately 78% nitrogen, 21% oxygen, and 0.9% argon. The analytical work will focus on detecting trace impurities such as nitrogen, argon, hydrogen, oxygen, and hydrocarbons, with measurement requirements at sub-ppb (parts per billion) levels. The document indicates that specific compounds of interest may vary depending on the bulk gas being analyzed, and no additional combination of sample gases beyond those specified is anticipated. The required lower detection limits are referenced but not explicitly detailed in this excerpt of the Q&A document.
