Hydrogen gas generators are the safer and more convenient alternative to helium for GC carrier gas. PEAK Scientific’s Precision Hydrogen Trace gas generators deliver up to 99.99999% hydrogen on demand. They provide a safer, more convenient and more reliable alternative to helium cylinders, which have been subject to significant price increases and supply disruption in recent years. The series includes standard hydrogen models for supplying detector gas, as well as zero air and nitrogen models, which can all be stacked, using minimal laboratory floor space for a complete GC gas solution. The latest hydrogen gas generator innovation includes PEAK Scientific’s Precision Hydrogen SL, as the smallest, simplest and safest laboratory hydrogen generator available on the market. Suitable for FID detectors, Precision SL produces GC detector hydrogen at 99.9995% purity.
