Hydrogen and High Purity Hydrogen Laboratory gas generators

High purity hydrogen generators for GC carrier gas and GCMS applications

The WM-H2, ND-H2, PAR-H2 and LC-H2 series hydrogen generators use the latest polymer electrolyte membrane (PEM) technology to produce pure hydrogen.

The ND-H2 series use a desiccant cartridge and the PAR-H2 unit use a single column dryer with programmable automatic regeneration via integrated calendar events. The LC-H2 series uses a desiccant cartridge which can be refilled or replaced by a new one.

HPD™ High Pressure Dispenser HPD™ High Pressure Dispenser

HPD™ High Pressure Dispenser

Traditional volumetric dispensers are designed for pipetting reagents or samples into vials or wells at ambient pressure or a few Bar at most. Online volumetric reagent delivery however, may require the ability to introduce reagents into a system with a high working pressure. The HPD™ was originally designed by Spark for SPE solvent delivery in on-line SPE-LC systems, but other applications are easy to imagine. Think of pre-column reagent addition for online derivatization in HPLC, post-column reagent addition for detection enhancement, etc.
