Packed column for the determination of methanol in waste gas
Packed column for the determination of methanol in waste gas Details:

Name: Packed Column

Chromatographic fixative: 5% polyethylene glycol
Carrier: graphite carbon black 80-120 mesh

Specifications: 2m*3mm, 2m*1/8

Model: 5%Carbowax 20M Carbopack B

Application: HJ T33-1999 Determination of methanol in exhaust gas from stationary pollution sources by gas chromatography



Methanol is the simplest saturated monohydric alcohol, and it is also an important chemical industry basic raw material and clean liquid fuel. It is widely used in organic synthesis, medicine, pesticides, coatings, dyes, automobiles and national defense industries. Methanol is highly toxic and can be poisoned by accidental drinking or long-term exposure. Therefore, relevant national standards have made corresponding regulations on the content of methanol in the air and the emission concentration of methanol from pollution sources. Corresponding methanol monitoring methods include HJ/T 33-1999 and gas chromatography and spectrophotometry of "Air and Waste Gas Monitoring and Analysis Methods (Supplement to the Fourth Edition)".

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses headspace gas chromatography to determine methanol content in industrial waste gas. The method is simple and fast. Distilled water is used to absorb methanol in the gas, and headspace injection is separated by graphitized carbon black column. Hydrogen flame ionization This method can meet the monitoring of industrial waste gas and methanol in the air.
