This standard specifies the determination method of furfuryl alcohol concentration in the air of workplace by gas chromatography.

This standard is applicable to the determination of furfuryl alcohol concentration in the air of workplace.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses activated carbon adsorption tube to collect furfuryl alcohol in the ambient air, and the ethanol is desorbed and determined by gas chromatography. The linear relationship of furfuryl alcohol is good within a certain concentration range. When the sampling volume is 30 L, the lowest detected mass concentration in the ambient air is 0.008 mg/m3. This method has simple pretreatment, good separation, and analytical precision and spiked recovery meet the requirements of analysis and testing, It is applicable to the determination of furfuryl alcohol in ambient air
