SAMPLE COLLECTION, THERMAL ANALYSIS, AND SAMPLE INJECTION APPARATUS AND METHOD, AND TRACE DETECTION DEVICE

摘要

A sample collection, thermal analysis, and sample injection apparatus, comprising: a sample collection structure (1); a piston-type adsorption device (2) having a adsorption chamber (2-2) in communication with the sample collection structure (1) and used for adsorbing collected samples; a piston tank (3) limited to accommodate the adsorption device (2) and a piston chamber (3-2) in communication with the adsorption chamber (2-2); a thermal analysis chamber (4) in communication with the adsorption chamber (2-2) and the piston chamber (3-2) for performing thermal analysis on samples adsorbed in the adsorption chamber (2-2); a pump (5) that is in communication with the piston chamber (3-2) via a tube (5-1) and sucks the sample in the ambient air via the sample collection structure (1) into the adsorption chamber (2-2). The adsorption device (2) is structured to move inside of the piston chamber (3-2) between a sample collection position and a sample analysis position. When at the collection position, the adsorption chamber (2-2) is positioned outside of the thermal analysis chamber (4) and is in communication with the sample collection structure (1) so as to adsorb the sample collected by the structure. When at the analysis position, the adsorption chamber (2-2) is positioned inside of the thermal analysis chamber (4) such that thermal analysis can be performed on the adsorbed sample in the thermal analysis chamber (4). Also provided are a sample collection and analysis method using the apparatus and a trace detection device.
