Detection of Ethylene Oxide and Propylene Oxide in Mainstream Cigarette Smoke
Detection of Ethylene Oxide and Propylene Oxide in Mainstream Cigarette Smoke Details:

Name: capillary column
Stationary Phase: Bonded Styrene-divinylbenzene
Specifications: 50m*0.32mm*10um
Model: HH-PLOT Q
Applications: Cigarettes Determination of Ethylene Oxide and Propylene Oxide in Mainstream Smoke Gas Chromatography-Mass Spectrometry

In order to simultaneously and accurately determine ethylene oxide and propylene oxide in mainstream cigarette smoke, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a cold trap-gas chromatography/mass spectrometry (GC/MS) method. The particulate matter in mainstream cigarette smoke was captured by a Cambridge filter, and the vapor in mainstream smoke was captured with toluene under cryogenic cold trap conditions. The ethylene oxide and propylene oxide in mainstream smoke of 21 domestic and foreign cigarettes with different tar content were determined. The results showed that: (1) The method had good linearity (R2≥0.999 7), the detection limits of ethylene oxide and propylene oxide were 0.03 μg/unit and 6.8 ng/unit, respectively, and the recoveries were between 91.0% and 101.5%. , The inter-day precision was between 2.4% and 6.0%. ②The releases of ethylene oxide and propylene oxide in mainstream smoke of 21 cigarette samples were 1.4-17.8 μg/cigarette and 158.8-1153.0 ng/cigarette, respectively. The method is simple in operation, accurate and reliable in results, and suitable for simultaneous determination of ethylene oxide and propylene oxide in mainstream cigarette smoke.
