Laboratory and Calibration Gases

About Laboratory and Calibration Gases

Laboratory gases and calibration gases are specialized for use as laboratory standards, as well as for detection, sample preparation, environmental monitoring, and analysis applications. Analytical or laboratory applications may include gas chromatography (GC, GC-MS, LC-MS), spectrometry (ICP, ICP-MS, Flame A.A., GFAA, NMR), specialty analysis techniques (thermal and elemental analysis, Total Organic Carbon analyzers) as well as sample or materials processing. Some analytical measurement instruments require specialty laboratory gases and calibration gases for instrument operation and/or calibration.

The purity, quantity, and type of laboratory gases and calibration gases used in an analytical instrument must be properly assessed based on the technique being used. For example, laboratory gases used in gas chromatography must be pure gases. Pure gases must adhere to specific industry purity standards. Helium, nitrogen, argon, hydrogen, oxygen, carbon dioxide, and acetylene must be determined pure to function properly in an analyzer. Nitrogen is often used as a calibration gas in spectroscopic equipment and may need to be determined as pure as 99.9995%. Gas purity can have a great effect on the outcome of an analytical laboratory procedure and must be taken into consideration when using a laboratory gas for sample preparation or measurement. Laboratory and calibration gases are also used in emission and absorption spectroscopy, mass spectroscopy, thermal and surface analyses, and liquid chromatography.
