System and method for testing the chemical contents of plastic containers, which move along a checking line

摘要

A system for testing of the chemical contents of a plurality of plastic containers, which is continuously move along a checking line. The system includes a detector, which is held on a first vacuum level, for the sequential receiving an air sample of each plastic enclosure of the plurality of plastic containers, while the same along the checking line, and for detecting the chemical contents of each sample. A line with a first end close to the plurality of plastic containers, and a second, distal end is provided. A sensor module, it is provided with the line between the first end and second end thereof connects. A vacuum pump is also provided which, together with the second end of the line is connected the inner side of the line to a second, lower vacuum level and to keep to form an air flow rate, in order to sequentially from the samples of plastic containers to be removed and to convey the same to the sensor module.
