This Technical Bulletin explains the gas chromatographic separation and detection of these gases. The composition of gasses in a system can indicate whether the system has developed a leak, oxidation or some other chemical reaction has occurred, or if the system has been correctly handled. Bubbles can develop in products through electrolysis, oxidation, or microbiological action.
Many processes require accurate control of the atmospheres.
The identity and purity of gasses in hospitals, manufacturing, medical devices, and products is very important. This Technical Bulletin explains the gas chromatographic separation and detection of these gasses. The fixed gasses are chromatographically separated based on molecular size. Samples are introduced using either a gas tight syringe or a sampling valve with a fixed volume loop. Upon injection the sample is swept through the GC with carrier gas.
