3 Terms and definitions

JC/T 2222 and defined by the following terms and definitions apply to this document. 3.1 Volatile organic compounds At 101.3 kPa standard atmospheric pressure, any organic compound with initial boiling point less than or equal to 250 ° C. 3.2 Total volatile organic compounds; TVOC Non-polar organic column separation, gas chromatography retention time between n-hexane and n-hexadecane volatile organic compounds Sum.

4 principle

The specimen is placed in the release chamber under certain conditions (temperature, humidity and air flow rate), the target component of the specimen released volatile organic compounds (VOC) is mixed with the air entering the release chamber and discharged from the outlet of the tank, and the adsorbent respectively collects a certain volume of Gas compounds, the choice of analytical instruments to capture the concentration of the release of the target component.

5 equipment

5.1 small release capsule system Small release system should meet the GB/T 29899-2013 Appendix A requirements. The typical operating conditions and control accuracy of the release tank are shown in Table 1.
