摘要

PROBLEM TO BE SOLVED: To provide a sampling container for collecting toxic materials in the air, capable of easily analyzing the toxic materials in the air in a fixed space at a low cost, and analyzing it at many places in a short period. SOLUTION: A porous thin film 8 for controlling ventilation is mounted on an opening part of the container A in which chemical substance is stored, and the container is exposed for a prescribed time in a fixed space in a house, a factory or the like. The toxic materials contained in the air in the space is taken into the container, and thereafter reacted with a chemical substance or adsorbed on the chemical substance, to thereby collect the toxic materials.
