冷冻机油中轻烃含量测定

Determination of the Light Components of Refrigerant Oil

利用顶空色谱法,在顶空瓶中把冷冻机油中轻质组分抽提出来,取瓶中气相部分用气相色谱法快速测定,测定结果表明样品中轻组分大部分是C6组分。大于C7的组分很少,该方法快速准确,可以满足样品的快速检测。

The light components of refrigerant oil can be extracted in headspace bottle,and quickly detected the gaseous phase in the bottle by gas chromatography,the main constituent of light components of sample was C6 and the content of constituents greater than C7 was less.The headspace chromatography method had the quickly and accuracy characters which can meet the rapidly detected need of sample.
