Glass column for determination of acetaldehyde in workplace air Details:

name: glass column

Fixative: FFAP

Carrier: Chromosowb W AW

Proportion: FFAP: Chromosowb G AW DMCS=15:100

Specifications: 1.6m*4mm inner diameter

Material: hard glass

Application: GB/T 17074-1997 Method for the determination of acetaldehyde in workshop air by solvent desorption gas chromatography.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a practical method for sampling and determination of acetaldehyde in workplace air. Results The method is simple, accurate and sensitive. The correlation coefficient of the standard curve was 0.999 5, the recovery rate of standard addition was 97.16%-104.63%, the relative standard deviation was 0.08%-0.29%, and the average sampling efficiency was 99.84%. Conclusion All the indicators of this method meet the requirements of "Development Specifications for Detection Methods of Air Toxicants in Workplace", and can accurately determine the content of acetaldehyde in the air.
