Many laboratories are now prohibited from placing Hydrogen cylinders on their premises owing to health and safety restrictions. A Peak Scientific Precision Hydrogen Trace generator is a safe alternative to gas cylinders whilst providing pure carrier gas (99.9999% purity, moisture free), in quantities great enough to supply a number of GCs simultaneously.
Technology Considerations on Hydrogen Generation Technology Hydrogen Generators that are utilised to provide Carrier Gas for GC and GC/MS applications employ many technologies to provide high purity hydrogen. Here were look at the various methods used to purify hydrogen. Three using PEM (Proton Exchange Membrane), combined with various purification techniques, and the fourth using a combined Palladium Electrolyser.
Several technologies are available for generating high-purity hydrogen, but palladium diffusers offer many advantages over the others.
Abstract The following technical brief aims to demonstrate the performance of GC-MS using hydrogen as a carrier gas. Here we compare the performance of hydrogen and helium for the analysis of a complex mixture. The results show that by using hydrogen, chromatographers can achieve superior results to helium, with faster run times and taller, sharper peaks.
Many labs are facing helium supply difficulties and rapid price increases as a result of the helium shortage. Lab managers are therefore looking for alternative carrier gases and for many GC applications, hydrogen provides an excellent alternative to helium. Using a hydrogen generator can supply gas to a whole lab and at the same time remove the danger of storing hydrogen in the lab. Laboratories that switch gas supply from helium to hydrogen can see a number of benefits including reduced overheads, faster throughput and even improved separations.
