Gas Chromatograph with Flame Ionization Detector

The National Institute of Standards and Technology (NIST) is seeking a gas chromatograph with a flame ionization detector. The device will be used to analyze ultra-high purity, inert bulk gases with expected purity of 99.999% or better. The primary gases to be sampled include nitrogen, air, helium, argon, and others. The device should be able to measure trace impurities at sub-ppb levels, with a lower detection limit of less than 1 ppb. The operating voltage should be 120 volts. Some key features of the required device include: • Ability to analyze ultra-high purity, inert bulk gases • Capability to measure trace impurities at sub-ppb levels • Lower detection limit of less than 1 ppb • Operating voltage of 120 volts • No requirement for a rack mount kit or an internal blender
