The main methods for determining methanol in the air include colorimetric method with red sulfite and gas chromatography The sensitivity of colorimetric method is 25 μ g/5ml, which cannot meet the needs of methanol determination in the environment
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the "Carbowax20M Carbopack B Filled Chromatography Column Shimadzu" for the determination of methanol in fixed pollution source exhaust gas, with high column efficiency and satisfactory results.
Name: Methanol specific packed column
Model: 5% Carbowax20M Carbopack B
Specification: 2m * 1/8, 80-120 mesh
Application: HJ/T 33-1999 Determination of Methanol in Fixed Source Exhaust Gas Gas Chromatography Method
This standard is applicable to the determination of methanol in organized and unorganized emissions from fixed pollution sources. The detection limit of the method is 2mg/m3 when the chromatographic injection volume is 1.0ml, calculated based on the peak height of the 3-fold noise chromatography; The concentration range for quantitative determination is 5.0-104mg/m3.
Applicable to:
Agilent 490 online/portable, 48905890689088608890
Shimadzu GC-14C, GC-2010, GC-2014, GC-2030
