HJ/T 35-1999 固定污染源排气中乙醛的测定 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乙醛测定。

1.2 当采样体积为100L，进样体积为1μL时，乙醛的检出限为4×10-2mg/m3，乙醛的定量测定浓度范围为0.14mg/m3-30mg/m3。

2 方法原理

用亚硫酸氢钠溶液采样，乙醛与亚硫酸氢钠发生亲核加成反应，在中性溶液中生成稳定的a-羟基磺酸盐，然后在稀碱溶液中共热释放出乙醛，经色谱柱分离，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。

HJ/T 35-1999 Determination of acetaldehyde in exhaust gas from stationary pollution sources-Gas chromatography
1 Scope of application

1.1 This standard applies to the determination of acetaldehyde in organized and unorganized emissions from stationary sources.

1.2 When the sampling volume is 100L and the injection volume is 1μL, the detection limit of acetaldehyde is 4×10-2mg/m3, and the quantitative determination concentration range of acetaldehyde is 0.14mg/m3-30mg/m3.

2 Principles of the method

Sampling with sodium bisulfite solution, acetaldehyde and sodium bisulfite undergo nucleophilic addition reaction to generate stable α-hydroxysulfonate in neutral solution, and then release acetaldehyde by co-heating in dilute alkali solution. The chromatographic column was separated, and the hydrogen flame ionization detector was used for determination.

Name: Packed glass column
Specifications: 2m*3mm (inner diameter), 2m*1/4
Model: 20%PEG-20M/GCS880 AW DMCS (80-100 mesh)
Application: HJ/T 35-1999 Determination of acetaldehyde in exhaust gas from stationary pollution sources-Gas chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., according to the size of Agilent 7820A, tailor-made a 2m*1/4 glass column dedicated to Agilent to measure the content of acetaldehyde in the exhaust gas of stationary pollution sources, quantified by external standard method, and the results are accurate and reliable .
