15% 聚乙二醇-20M / Chromosorb W AW DMCS 填充柱 测定废气中丙烯醛，这是一个非常经典且可靠的气相色谱分析方法。
采用填充柱气相色谱-氢火焰离子化检测器（GC-FID）对废气中的丙烯醛进行定性和定量分析。样品经采集后（通常使用吸收瓶或气袋），直接或经过稀释后注入气相色谱系统。目标化合物在色谱柱上实现分离，并由FID检测器进行检测。
方法原理
-
采样：废气中的丙烯醛用蒸馏水或合适的吸收液（如2,4-二硝基苯肼衍生化法，但本方法为直接进样）采集。
-
分离：气态样品通过进样口进入色谱系统。在载气的带动下，样品流经色谱柱。
固定相：聚乙二醇-20M (PEG-20M) 是一种极性固定液，对含羰基（C=O）、羟基（-OH）的化合物有较好的保留和分离能力。
- 载体：Chromosorb W AW DMCS 是经过酸洗（AW）和二甲基二氯硅烷（DMCS）处理的硅藻土载体，表面惰性好，能有效减少极性化合物（如丙烯醛）的拖尾和吸附现象。
- 15% 的涂渍量属于高配比，提供了足够的固定相以充分分离挥发性有机极性化合物。
-
检测：分离后的组分依次进入FID检测器。丙烯醛在氢火焰中燃烧产生离子，这些离子被收集极捕获形成电信号，其强度与组分的质量成正比。
-
定性与定量：通过对比样品和标准品的保留时间进行定性，采用外标法或内标法进行定量分析。

The determination of acrolein in exhaust gas using a 15% PEG-20M/Chromosorb W AW DMCS packed column is a very classic and reliable gas chromatography analysis method.
Qualitative and quantitative analysis of acrolein in exhaust gas was performed using packed column gas chromatography hydrogen flame ionization detector (GC-FID). After the sample is collected (usually using an absorption bottle or gas bag), it is injected directly or diluted into a gas chromatography system. The target compound is separated on a chromatographic column and detected by a FID detector.
Method principle
Sampling: Acrolein in the exhaust gas is collected using distilled water or a suitable absorption solution (such as 2,4-dinitrophenylhydrazine derivatization method, but this method involves direct injection).
Separation: Gaseous samples enter the chromatography system through the injection port. Driven by the carrier gas, the sample flows through the chromatographic column.
Fixed phase: PEG-20M is a polar stationary phase with good retention and separation ability for compounds containing carbonyl (C=O) and hydroxyl (- OH) groups.
Carrier: Chromosorb W AW DMCS is a diatomaceous earth carrier treated with acid washing (AW) and dimethyl dichlorosilane (DMCS). It has a good surface inertness and can effectively reduce the tailing and adsorption of polar compounds such as acrolein.
A coating amount of 15% belongs to a high proportion, providing sufficient stationary phase to fully separate volatile organic polar compounds.
Detection: The separated components enter the FID detector in sequence. Acrolein burns in a hydrogen flame to produce ions, which are captured by the collection electrode to form an electrical signal whose intensity is proportional to the mass of the component.
Qualitative and quantitative analysis: Qualitative analysis is conducted by comparing the retention time of samples and standards, and quantitative analysis is performed using external or internal standard methods.
