Model: HH-CH4-GC Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and develops a portable methane reformer gas chromatography method to measure the concentration of carbon monoxide in the air (or gas) in coal mines. The external standard method is quantitative, and the results are accurate and reliable. It was installed and used on the Agilent 7820A gas chromatograph and achieved good results.Agilent 7890B uses portable methane converter

Details of the portable methane converter used by Agilent 7890B:



Name: portable methane converter

Model: HH-CH4-GC

Application: Determination of trace carbon oxide, methane and carbon dioxide in gas I Gas chromatography



Suitable for: Agilent 4890. 5890, 6890, 7890, 7820, 8860, 8890 gas chromatograph

Features: external type, seamless connection can be realized without instrument modification; Vast chromatography, a unique product.



Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses a portable hydrogen flame ionization gas chromatograph with a nickel converter to determine trace carbon monoxide and carbon dioxide in polymer grade propylene. The influence of the operating parameters of the gas chromatograph on the determination results was investigated. The results showed that the better analysis conditions of the Agilent 7890A gas chromatograph were: column temperature of 50 ℃, carrier gas flow rate of 14.8 mL/min, sample volume of 2 mL, and valve switching time of 1.8 min. Under this condition, the recovery rate of carbon monoxide and carbon dioxide in the standard gas is 94%~101%, and the relative standard deviation of samples with different concentrations is 3.21%~5.68%. The accuracy and precision meet the standard requirements.
