  • Supplying High-Purity Gases: Making a Case for In-House Gas Generators (.pdf)
    Selecting the most effective source for high-purity gases is a critical issue for laboratory managers. Zero air and hydrogen are used for gas chromatography with flame ionization detection (GC-FID), and nitrogen is used for high-performance liquid chromatography or gas chromatography with mass

  • How To Select a Total Hydrocarbon Analyzer For Use in an Industrial Application (.pdf)
    Several different sensor technologies may be used to detect hydrocarbons, including: catalytic; photo-ionization; infra-red; gas chromatography; and flame ionization. Of these possibilities, flame ionization (FID) is considered the best choice for continuously monitoring the total concentration
