Establish a gas chromatography direct determination method for carbon dioxide in the air using Haohan chromatography. The separation of carbon dioxide, oxygen, and nitrogen in the air was carried out using HQ packed columns, and determined using TCD. The results show that the detection limit of carbon dioxide in the air using this method is 181 mg/m~3, and the injection amount is 1ml of gas. The reproducibility of the method meets the requirements, with a relative standard deviation of 1.7% to 9.1%. The sample can be stored at room temperature for 7 days. Reminder: This method is suitable for detecting carbon dioxide content in the air of workplaces.
