Abstract

Adsorbents used to analyze air for concentrations of various organic compounds with their subsequent determination by thermal desorption gas chromatography–mass spectrometry (GC–MS) are considered. Tenax-TA is the most commonly used material for such tasks, but it has drawbacks. The characteristics of adsorbents of Tenax, Carbosieve, Carboxen, Carbotrap, Capbopack, Porapak, Chromosorb families, XAD polymer resins, activated carbons, and some monolithic carbon materials are given. Their advantages and disadvantages for the adsorption/thermal desorption of hydrocarbons are discussed. The advantages of monolithic carbon materials and the need in the development of a new domestic material for analytical gas chromatography–thermal desorption mass spectrometry in solving oil-prospecting problems are substantiated.

基于碳材料的被动吸附剂及其用于估算岩石油气潜力的比较

摘要

吸附剂用于分析空气中各种有机化合物的浓度，随后通过热解吸气相色谱-质谱 (GC-MS) 进行测定。Tenax-TA 是此类任务最常用的材料，但它也有缺点。给出了 Tenax、Carbosieve、Carboxen、Carbotrap、Capbopack、Porapak、Chromosorb 系列、XAD 聚合物树脂、活性炭和一些整体碳材料的吸附剂的特性。讨论了它们对烃类吸附/热解吸的优缺点。单片碳材料的优势以及开发用于分析气相色谱-热解吸质谱的新型国产材料在解决石油勘探问题方面的需求得到了证实。
