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.
