DISSIPATION AMOUNT MEASURING METHOD OF SEMI-VOLATILE ORGANIC COMPOUND, AND DISSIPATION AMOUNT MEASURING DEVICE OF SEMI-VOLATILE ORGANIC COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a dissipation amount measuring method and a measuring device of a semi-volatile organic compound capable of determining more accurately with high precision, the dissipation amount of the semi-volatile organic compound (SVOC) from a measuring object. SOLUTION: This method for measuring the dissipation amount of the semi-volatile organic compound dissipating from the measuring object 2 is described as follows: the measuring object 2 and a standard material generation source 4 for generating a standard material not dissipating from the measuring object 2 are arranged in a chamber 3, and a specific point P in the chamber 3 is determined as a concentration measuring position; a one-directional laminar air flow is generated in the chamber 3, and the air is collected on the concentration measuring position in this state; a concentration of the semi-volatile organic compound and a concentration of the standard material in the collected air are measured; and the dissipation amount of the semi-volatile organic compound is determined by correcting a concentration measurement result of the semi-volatile organic compound based on a relation between a concentration measurement result of the standard material and a theoretical concentration of the standard material. As the specific point P in the chamber 3, a point on the downstream side of the measuring object 2 in the one-directional laminar air flow is selected. COPYRIGHT: (C)2010,JPO&INPIT
