The HydroGen series HG ST PRO is able to generate up to 600 cc/min Hydrogen with purity better than 99.99999% and  pressure up to 16 bar (232 PSI). The HG ST PRO includes an electrolytic cell with polymeric membrane (PEM) using distilled water.  The two-column PSA drying system with automatic regeneration ensures the maximum grade of hydrogen purity, and is completely maintenance-free. The HG ST PRO is the ideal Hydrogen for all GC-FID detectors. The on-board CPU  constantly control the operating parameters to guarantee full safety. Up to 20 units can be connected in parallel mode using an external control box.
