中間セル方式ガスクロマトグラフにおける Porapak の利用と貯蔵食品の呼吸測定への応用(園芸農学)

摘要

A method is described for determing microquantity of CO_2 and O_2 by the gas chromatograph equipped a two-stage column. Helium is used as the carrier gas and Porapak Q and molecular sieve as the adsorbents. This method is very sensitive and accurate for a
