Capillary column for monitoring air environment in furfuryl alcohol production workshop
Capillary column for monitoring air environment in furfuryl alcohol production workshop Details:

Name: capillary column

Fixative: polyethylene glycol

Specifications: 30m*0.32mm*0.5mm

Model: HH-FFAP

Application: Determination of Toxic Substances in Workplace Air Part 170: Furfuryl Alcohol


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a sampling tube equipped with Tenax-TA adsorbent to collect furfuryl alcohol and furfural in the air of the workshop, and used gas chromatography for qualitative and quantitative detection. Under the given test conditions, the detection limits of this method were 1.06 mg/m~3 for furfuryl alcohol and 0.17 mg/m~3 for furfural, respectively, the average desorption efficiencies were 95.7% for furfuryl alcohol and 92.6% for furfural, and the coefficients of variation were 3.0 for furfuryl alcohol, respectively. %～5.2%, furfural 3.8%～6.1%. The breakthrough capacities of Tenax-TA for furfuryl alcohol and furfural were greater than 16.7 and 13.5 mg, respectively. After field test, the method can be used for sanitary monitoring of furfuryl alcohol production workshop.
