The Use Of Nafion Dryer Tubes For Moisture Removal In Flow Injection Chemical Vapor Generation Atomic Absorption Spectrometry, Ng Sundin, Julian Tyson, C P. Hanna, S A. Mcintosh

Chemistry Department Faculty Publication Series

A significant problem with flow injection chemical vapor generation atomic absorption spectrometry is a loss of sensitivity and blockage of transfer lines due to excessive moisture transported to the atom cell or lodged in the transfer line. A Nafion dryer tube was used to remove moisture from the wet carrier gas stream. The hygroscopic Nafion membrane removed water at 1.7 mg/min at an efficiency of 95 ± 4% when SnCl2 was used as the reductant. When 0.4% (m/v) borohydride was used as the reductant, 2.3 mg/min of water was removed at an efficiency of 91 ± 3%. No measurable change …
