Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a capillary column gas chromatography method for the determination of methanol in the air. The method uses a silica gel tube to adsorb methanol in the air, absorbs it by water, and determines it by a capillary column gas chromatograph. Results The methanol concentration is between 0 and 250 The linear relationship is good in the range of μg/ml, the linear equation is y=5.79x+25.67, the correlation coefficient r=0.999 7, and the detection limit is 0.10 μg/ml. If a 1.5 L air sample is collected, the minimum detection concentration is 0.07 mg /m3, the average recovery rate of standard addition is 91.91%～97.09%. Conclusion The method is sensitive and accurate, and is suitable for the determination of methanol in workplace air.
