Abstract:
A gas chromatographic procedure is described that permits rapid, specific, and precise determination of N 2 , O 2 , Ar, CO 2 , CH 4 , N 2 O, and other gases in soil atmospheres. It involves use of an ultrasonic detector and two columns of Porapak Q at different temperatures, and it does not require temperature programming, column conditioning, stream splitting, column switching, or switching of recorder polarity. Unlike thermal conductivity and helium ionization detectors previously used for gas chromatographic analysis of soil atmospheres, the ultrasonic detector is not adversely affected by gases found in soil atmospheres and permits determination of these gases at concentrations ranging from 〈 10 ng/ml to 100%.
