    Abstract

    For the improvement of the air quality of indoors, it is necessary to determine the kinds and the concentration of the chemical substances that emit from building products and production parts. On this study, the heating temperature, the amount of the nitrogen filling, and the heating time, etc. was executed as an important item related to the measurement of bag method. It was a tendency that the recovery percentage raises with the rise of the heating temperature as a result of examining the recovery percentage by using the standard test solution, too. Therefore, 65 degrees of the heating temperature is preferable. However, the recovery percentage is less than 80% at even 65 degrees in heating temperature, and it has been understood that it is unsuitable in the measurement in the bag method in Tetradecan. In addition, it has been understood that the bag value calculated from the chamber method becomes small more than the bag value calculated from the bag method.
