Determination of Occupational Exposure Limit of Acetaldehyde in the Air of Workshop
Determination of Occupational Exposure Limit for Acetaldehyde in the Air of 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 practical method for sampling and determination of acetaldehyde in the workplace air. Results The method is simple, accurate and highly sensitive. The correlation coefficient of the standard curve is 0.999 5, the recovery of standard addition is 97.16%~104.63%, the relative standard deviation is 0.08%~0.29%, and the average sampling efficiency is 99.84%. Conclusion All indicators of this method meet the requirements of "Development Specification for Air Poison Detection Methods in Workplaces", and can accurately determine the content of acetaldehyde in the air.
