GAS CHROMATOGRAPHIC ANALYSIS OF HEAD SPACE GAS OF DILUTE AQUEOUS SOLUTIONS

Enrichment of head space gas in sulfides, carbonyls, esters, and alcohols prior to chromatographic analyses was accomplished by adding anhydrous sodium sulfate salt to dilute aqueous solutions. It was possible to analyze head space gas from aqueous solutions below the 1 p.p.m. level. In addition to retention times, evidence for identification of these trace organic compounds was obtained by eliminating peaks with selective qualitative reagents. Evidence for the identification of the 18 components of a complex mixture of sulfides, carbonyls, esters, and alcohols at the 1 p.p.m. carbonyls was made to establish the limits of sensitivity of the method.
