The 5% Carbowax 20M/Carbopack B packed column specified in HJ/T 33-1999 standard is a classic choice for determining methanol in exhaust gas from fixed pollution sources. It has high column efficiency, good selectivity for methanol, and can effectively eliminate common interfering substances.
Advantages and limitations of the method:
The HJ/T 33-1999 method is a classic methanol determination method with stable packed column performance.
Its detection limit and quantitative range can meet the requirements of most fixed pollution source emission monitoring.
Standard solution and curve:
Methanol standard gas can be diluted step by step with high-purity nitrogen using a 100mL glass syringe to obtain 5. It is best to draw a calibration curve before each startup analysis, and regularly calibrate it with standard samples during the analysis process to ensure accurate quantification.
Instrument compatibility: This packed column is compatible with multiple gas chromatograph brands and models (such as Agilent, Shimadzu, Thermo Fisher, Varian, etc.)
This packed column (5% Carbowax 20M/Carbopack B) can effectively separate components such as methanol, acetaldehyde, acetone, and ethanol, avoiding interference from these common substances in methanol determination.
If the sample composition is complex and there are doubts about the qualitative analysis of the methanol peak, it is recommended to use dual column qualitative analysis or chromatography/mass spectrometry (GC-MS) for further confirmation.
Name: Methanol specific packed column
Model: 5% Carbowax20M Carbopack B
Specification: 2m * 3mm, 80-120 mesh
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the Shimadzu chromatography column for the determination of methanol in exhaust gas from fixed pollution sources. The column has high efficiency, good separation, and symmetrical peak shapes. The recovery rate measured by standard addition method is between 101% and 103%, and the relative standard deviation (n=5) of the measured values is less than 2%. The results are satisfactory.
Suitable for:
Agilent 490 online/portable, 48905890689088608890
Shimadzu GC-14C, GC-2010, GC-2014, GC-2030
