Hydrogen gas generators use a proton exchange membrane (PEM) to produce hydrogen gas from water. The PEM cell was originally developed by NASA and is extensively used in industrial and laboratory applications.
In a recent white paper, Restek corporation identified a simple methodology for the simple comparison of e-cigarette liquids using GC-MS and GC-FID.
Method implications on lab gas supply for Residual Solvent Analysis using HS-GC-FID - as featured in The European Pharmaceutical Manufacturer Magazine.
The Precision generator range has been designed to produce ultra-high purity (UHP) gases to supply GC applications for carrier and detector gas supply.
Background Researchers from Prof. Guido Verbeck’s group at the University of North Texas (UNT) carried out analysis of drugs of abuse (DOA) and explosives using an ion trap GC-MS to compare results when using helium and hydrogen carrier and buffer gas. As well as comparing the two gases, the group also assessed a number of ion volumes with different orifice diameters to look at their effect on sensitivity with either gas.
