Peak Scientific has extended its range of hydrogen generators with the Precision Hydrogen Trace 250. The new, smaller model sits alongside the existing Hydrogen Trace 500, to offer a more cost-effective solution for those requiring lower flow rates, such as labs with only one or two instruments. The new Hydrogen Trace 250 features new innovations in trace dryer technology that ensures ultra-high purity performance. For those currently using hydrogen or considering hydrogen as a carrier gas for GC and GC-MS, this generator delivers 250 cm3 min–1 of hydrogen at 99.9999% purity. Incorporating the same compact, modular form factor as all Precision units allows users to build a Precision stack to meet their specific application’s gas requirements, whilst taking up minimal laboratory floor space.
