摘要:
以1个典型食品生产企业(酱菜厂)周边的异味挥发性有机物监测为例,介绍了罐采样-GC/MS、便携式GC/MS、SPME-GC/MS以及SPME-异味分析系统等4种监测方法的实际应用,从定性、定量监测结果等方面,比较了4种监测方法的特点。罐采样-GC/MS、便携式GC-MS 2种方法适用于定性、定量检测,在有标准样品的前提下,定量结果总体可比;SPME-GC/MS以及SPME-异味分析系统2种方法更适用于定性检测。

Abstract:
The four detection methods for odorous organic compounds in the ambient air around a typical food industry (pickles factory) were introduced, including Canister sampling GC/MS, Portable GC MS, SPME GC/MS and SPME off flavor analyzer. Based on the qualitative and quantitative results, the characteristics of the four methods were compared. Both methods of Canister sampling GC/MS and Portable GC MS were suitable to qualitation and quantitation, and their quantitative results were comparable when calibrated with the standard samples. While the methods of SPME GC/MS and SPME off flavor analyzer preferred to qualitation.
