HJ/T 36-1999标准中，使用GDX-502填充柱（3m×4mm, 60-80目），采用直接进样-气相色谱法（FID检测器） 是测定固定污染源排气中丙烯醛的经典方法
这个方法适用于固定污染源有组织排放（如烟囱、排气筒）和无组织排放（如厂界无组织逸散）的丙烯醛测定。
方法原理：排气中的丙烯醛（CH₂CHCHO）样品直接注射进入气相色谱仪，经GDX-502色谱柱分离后，用氢火焰离子化检测器（FID） 进行检测。通过对比标准样品色谱峰的保留时间进行定性分析，利用峰高（或峰面积）进行定量分析1。
方法性能：该方法的检出限为0.1 mg/m³。当进样体积为1毫升时，定量测定范围一般为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 ₂ 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.
