Abstract

In this study, design and construction of a PRECONCENTRATION system for determination of trace impurities in ultra PURE HYDROGEN were performed. PRECONCENTRATION of impurities was done by adsorption of impurities on SILICA GEL (as adsorbent) in liquid nitrogen temperature (77K). Expriments were carried out by a gas chromatograph equipped with TCD and FID detectors, molecular sieve 5 A, and propack Q columns, for optimization of theoric values from calculations. The optiumum conditions have been determined by expriments: as adsorbent (silica gel 70-230 mesh, chromatography grade, 1 g), PRECONCENTRATION column: 1.4 inch×5 cm copper tube, hydrogen flow rate in PRECONCENTRATION process: 100 ml/min.
