Adsorption gas chromatography using water vapor as the carrier gas for organic substances containing oxygen

This paper reports a new method for the determination of sludge water content by a multiple headspace extraction gas chromatographic (MHE-GC) method. It is based on the water vapor signals in the sample vial from the first five extractions.

Abstract A fast and direct method is presented for the determination of CO2 in wines. Partial pressures from other ingredients of alcoholic beverages do not interfere. The method was compared to the manometric procedure under vacuum. An F & M Model 450 Gas Chromatograph with a filament detector was used for C02 determinations. Components were separated by a column 9” long and 1/8” o.d. using charcoal (60—80 mesh) as solid adsorbent. Injection port temperature was ambient; detector and column temperatures were 40°C. Helium was used as a carrier gas at the rate of 50 ml/min. Approximately 50 μ1 samples of standard and unknown solutions were used for the respective determinations.
