improved gas chromatograms with Elhygen* R are a matter of record The more sensitive your analyzer, the greater your need for an Elhygen R. This electrolytic generator employs a unique palladium diffusion process to produce ultrapure, ultradry hydrogen for noise-free flame ionization detector analyses and critical carrier gas
applications. Elhygen R continuously produces up to 150 milliliters/minute hydrogen (STP) with output pressure adjustable from 0 to 60 psig, ±0.025psi...enough to support two dual flame F.I.D.’s. Operating cost is less than 20 per 100 liters, and one liter of distilled water produces 1000 liters of dry hydrogen with less than 10 parts per billion total impurities.
a
Elhygen R never contains more than few milliliters of hydrogen at any one
time, eliminating the explosion hazard of stored H2. Best of all, this precisionregulated generator, complete with electrolyte, costs only $659.00, F.O.B. Factory, and comes with a full year’s warranty.
