HJ/T 36-1999標準中，使用GDX-502填充柱（3m×4mm, 60-80目），采用直接進樣-氣相色譜法（FID檢測器） 是測定固定污染源排氣中丙烯醛的經(jīng)典方法
這個方法適用于固定污染源有組織排放（如煙囪、排氣筒）和無組織排放（如廠界無組織逸散）的丙烯醛測定。
方法原理：排氣中的丙烯醛（CH?CHCHO）樣品直接注射進入氣相色譜儀，經(jīng)GDX-502色譜柱分離后，用氫火焰離子化檢測器（FID） 進行檢測。通過對比標準樣品色譜峰的保留時間進行定性分析，利用峰高（或峰面積）進行定量分析1。
方法性能：該方法的檢出限為0.1 mg/m³。當進樣體積為1毫升時，定量測定范圍一般為0.31 mg/m³ ~ 100.0 mg/m³

In the HJ/T 36-1999 standard, the use of GDX-502 packed column (3m × 4mm, 60-80 mesh) and direct injection gas chromatography (FID detector) is a classic method for determining acrolein in exhaust gas from fixed pollution sources
This method is applicable for the determination of acrolein in organized emissions (such as chimneys and exhaust pipes) and unorganized emissions (such as unorganized emissions at the factory boundary) from fixed pollution sources.
Method principle: The sample of acrolein (CH ? CHCHO) in the exhaust is directly injected into the gas chromatograph, separated by the GDX-502 chromatographic column, and detected using a hydrogen flame ionization detector (FID). Qualitative analysis is performed by comparing the retention time of chromatographic peaks of standard samples, and quantitative analysis is performed using peak height (or peak area).
Method performance: The detection limit of this method is 0.1 mg/m ³. When the injection volume is 1 milliliter, the quantitative determination range is generally between 0.31 mg/m ³ and 100.0 mg/m ³
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses GDX502 glass chromatography column to determine formaldehyde in exhaust gas from fixed pollution sources, and uses area external standard method for quantification. It has been installed and used on Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, and PE with good results.
