Carbon Dioxide
CO2 44.01
[124-38-9]
This product contains CO2 not less than 99.5% (ml/ml).
[Properties] This product is a colorless gas; odorless; the aqueous solution shows a weak acid reaction.
This product can dissolve in about 1 volume of water when 1 volume is at 20℃ under normal pressure.

Hydrocarbons take this product as the test sample; take the gas with a methane content of 0.0020% (with nitrogen as the diluent) as the control gas, and test according to the gas chromatography (general rule 0521), using a glass ball as the packing column (0.8 m×4mm, 80 mesh); column temperature is 110℃; injection port temperature is 110℃; detector temperature is 120℃. Measure the test gas and control gas and inject them into the gas chromatograph. The peak area measured when the purification temperature is 360°C is the corresponding blank value; measure the test gas and control gas and inject them into the gas chromatograph to determine the peak area , The peak area after subtracting the corresponding blank value is the corrected peak area. According to the external standard method to calibrate the peak area, the content of hydrocarbons (calculated as methane) shall not exceed 0.0020%.
