VOC Analysis: O.I. Analytical Nitrogen Purge Gas Application Note with Restek Rtx-624 GC Column

The thought of N2 gas for purge & trap / GC-MS of volatile organic compounds has been around for years. N2 GC carrier gas decreases MS sensitivity and has unfavorable performance for analysis time versus helium. O.I. Analytical found a novel approach to this problem; they use N2 for purge gas and helium as GC … Continue reading VOC Analysis: O.I.
