型号：HH-790CH4-GC
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. proposed a reaction-gas chromatography method for the determination of trace CO and CO2 gases. The relationship between the flow rate of the carrier gas, the reaction temperature and the location of the catalyst device and the conversion of CO and CO2 to CH4 were tested. The best conditions were obtained: carrier gas flow rate 40-60 mL/min; reaction temperature: CO3 65°C, CO2 360°C; separation temperature 60°C. Taking the Agilent 7890B and the standard gas of the Standard Metrology Institute as a reference, the self-prepared gas was measured, and satisfactory results were obtained. The relative deviation of the method is below ±5%, and this method is also suitable for the determination of trace carbon in metals. To

The features of this instrument are: a portable methane reformer; when the trace amount of carbon monoxide and carbon dioxide is not analyzed, the portable methane reformer is removed. The instrument does not need to be modified, and it is versatile and can achieve the purpose of one machine with multiple uses.
