低温预浓缩系统GC-MS联用测定色拉油油烟气中痕量挥发性有机物

Determination of Trace Volatile Organic Compounds in Cooking Salad Oil Fume by Preconcentrator-GC-MS

应用低温预浓缩系统GC-MS法对色拉油油烟气进行全分析,方法简便、灵敏度高、仪器检测性能稳定。油烟气中共检出69种挥发性有机化合物,包括脂肪烃、醛、酚、酯、氧杂化合物等多种对人体健康有害的物质,易引起呼吸系统疾病。

The preconcentrator-GC-MS was evaluated for determination of 69 kinds of trace volatile organic compounds in the cooking oil fume. The results showed that this method was convenient, sensitive and steady. Most of the detected compounds had harmful effect on human health, such as hydrocarbons, aldehydes, phenols, eaters and oxygen heterocyclic compounds, etc. They often caused the respiratory system diseases.
