Determination of occupational exposure limit for acetaldehyde in the air of the workshop Details:

Name: Spiral stainless steel column
Stationary phase: use 20% polyethylene glycol 20M as the stationary liquid, and coat it on the 6201 glazed support (60^80 mesh)
Specification: 2m*4mm (inner diameter)

Application: GB 18529-2001 Occupational exposure limit of acetaldehyde in the air of workplace




Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established a gas chromatography method for acetaldehyde in the air of workplaces. Methods The acetaldehyde in the air was adsorbed by silica gel tube, separated by chromatographic column, and detected by FID detector. Results The linear range of the method was 39~780μg/ml, the regression equation was y=2.127 3x-8.486 3(r=0.999 9), the detection limit was 0.6μg/ml, the desorption efficiency was 88.4%-93.3%, and the relative standard deviation It is 1.4%~2.0%. Conclusion The method is fast, sensitive and accurate, and it is suitable for the detection of acetaldehyde in the air in the workplace.
