Determination of Propylene Oxide in Workshop Air by Gas Chromatography
Gas Chromatographic Determination of Propylene Oxide in Workshop Air Details:

Name: capillary column

Fixative: polyethylene glycol-20M

Specifications: 30m*0.32mm*0.25um

Model: PEG-20M
Application: Gas Chromatographic Determination of Propylene Oxide in Workshop Air

In the R&D workshop of Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., propylene oxide in the air can be sampled by activated carbon tube, desorbed by butanol, separated by PEG-20M chromatographic column, and detected by hydrogen flame ionization detector. Under the given conditions, the detection limit of the method is 1.4×10(-3)μg/2μl, the minimum detection concentration is 0.35mg/m3 (2L gas extraction), and the penetration capacity is 1.8mg/200mg activated carbon; the precision, The desorption efficiency and the storage stability of the samples all meet the requirements. It has been tested and verified that this method can be used for industrial hygiene monitoring.
