为了解决空气中瞬间低浓度醇、酯类有机化合物浓度的测定，对ＤＣ５５０／红色硅藻土作浓缩吸附剂进行了研究，结果表明：该吸附剂对醇、酯类有机化合物的浓缩回收率在９４％～１０５．２％，现场也得到了同样的验证。从而可较好地解决空气中醇、酯类化合物低浓度的测定问题。
In order to solve the problem of the instant low concentration of alcohol and ester organic compounds in air, the concentration of DC550 / red diatomite as adsorbent was studied. The results showed that the concentration of alcohol and ester organic compounds was 94% ~ 105.2%, the scene also got the same verification. Which can be a good solution to the determination of low concentrations of alcohols and esters in the air.
