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 spectrometric detection (LC-MS or GC-MS). High purity gases are used with other instruments: CO2 free purge gase for Fourier transform infrared spectroscopy (FT-IR), highly purified nitrogen for inductively coupled plasma (ICP) systems, dry air for nuclear resonance spectroscopy (NMR) and hydrocarbon-free combustion gas for TOC analyzers.
Many laboratories employ in-house high purity gas generation to supply the necessary gases, as they provide significant safety, convenience and cost advantage when compared to the use of tank gas.
