GDX-502填充柱 固定污染源排气中丙烯醛的测定 气相色谱法

1 适用范围

1.1 本标准适用于固定污染源有组织排放和无组织排放的丙烯醛测定。

1.2 本标准的检出限为0.1mg/m³,当进样量为1ml时，定量测定的浓度范围为0.31~1.0×10²mg/m³。

2 方法原理

丙烯醛（CH₂CHCHO）直接进样，在色谱柱中与其它物质分离后，用氢火焰离子化检测器测定，以标准样品色谱峰的保留时间定性、峰高定量。


Determination of acrolein in exhaust gas from stationary pollution sources by gas chromatography
Determination of acrolein in exhaust gas from stationary pollution sources by gas chromatography Details:

name: glass column
Specifications: 3m*4mm
Granularity: 60-80 mesh
Model: GDX-502
Application: HJ/T 36-1999 Determination of acrolein in exhaust gas from stationary pollution sources-Gas chromatography

1 Scope of application

1.1 This standard is applicable to the determination of acrolein in organized and unorganized emissions from stationary pollution sources.

1.2 The detection limit of this standard is 0.1mg/m3. When the injection volume is 1ml, the concentration range of quantitative determination is 0.31~1.0×102mg/m3.

2 Principles of the method

Acrolein (CH2CHCHO) was directly injected into the sample, and after being separated from other substances in the chromatographic column, it was measured with a hydrogen flame ionization detector, and the chromatographic peak retention time of the standard sample was used for qualitative determination and peak height for quantitative determination.
