Abstract: | "Objective: To discuss the stability of mixed standard application solution by volatilization organic matter (benzene, toluene, xylene, ethylbenzene, acetone, butanone, Ethyl acetate, butyl ester, trichloroethylene) in workplace air. Methods: A total of 11 kinds volatilization organic compounds were separated by capillary chromatographic column, and detected with flame ionization detector. The stability of mixed standard application solution was judged by studying three paratemers during the placement period, such as the linear correlation coefficient of the standard curve, the relative response values of the highest and lowest concentration levels and the accuracy of the measured values of the quality control samples. Results: Within 187 days, the linear correlation coefficient of each compound was >/=0.999. The changes of relative response values at the highest and lowest concentration levels were both <10%; The measured values of toluene were all in the reference range. Conclusion: The mixed standard application solution is stable and reliable within 187 days of storage" |
