Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the China Petroleum and Chemical Industry Federation. This standard is under the jurisdiction of the National Gas Standardization Technical Committee Gas Analysis Subcommittee (SAC/TC206/SC1). This standard was drafted. China Testing Technology Research Institute. The main drafters of this standard. Tan Heping, Qian Shanshan, Sun Dengfeng, Fang Zheng, Zhang Yunqi, Shi Xiefei. Determination of volatile harmful organic compounds in gas analysis "SUMMA tank - silanization tube" sampling gas chromatography / Mass spectrometry (GC/MS)

1 Scope

This standard specifies the SUMMA tank sampling-gas chromatography/mass spectrometry for the determination of volatile hazardous organic compounds in indoor air. This standard applies to the determination of 19 volatile organic compounds in air such as residential buildings, office buildings, environmental test chambers (see Appendix A), and His indoor volatile organic compounds (see Appendix B) are measured. Determination of volatile organic compounds in other indoor air can refer to this standard carried out.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Volatile organic compound volatileorganiccompound; VOC Volatile Organic Compounds and Volatile Organic Compounds as defined in Chapter 3 of ISO 16000-6.2011 Two kinds of organic substances (very volatileorganiccompound).

4 Principle of the method

The indoor air sample is collected by a stainless steel tank with a tank pressure of less than 10 Pa inerted by the inner wall, concentrated by cold trap, and desorbed by heating. After that, the gas chromatograph is separated by a capillary column and detected by a mass spectrometer. Pass with standard mass spectrometry database and retention time The comparison is qualitative, and the external standard method is quantitative. ......
