DEVICE FOR QUICKLY EXTRACTING MULTIPLE SAMPLES OF GASEOUS CHEMICALS

摘要

The present invention relates to a device for quickly extracting multiple samples of gaseous chemicals, which comprises: a collection tube having an inner extraction space and an open lower part; a sample suction part arranged on the upper part of the collection tube consisting of a suction tube connected to the inner extraction space of the collection tube and a valve arranged in the suction tube so as to open or close the suction tube; and a plunger connected to the inner extraction space of the collection tube for evacuating the extraction space, whereby multiple extraction containers may be readily carried on a connection plate so that it is possible to collect samples of the atmosphere in several positions, and also the multiple extraction containers may be readily evacuated beforehand or later on the site.
