ABSTRACT:
A system for quickly and automatically extracting and analysing residual solvents is realised for operating directly in the premises where the packing materials are being manufactured, printed and/or laminated.The system provides for a single unit equipped with a display and a keyboard, and comprises an extraction (desorption) chamber (1), an analysis chamber with valves and separating columns, a detection system (17), and a data processing system (19).The extracting or desorption chamber comprises a desorption cell (1) for receiving a vial (36; 37) containing said sample, and means are provided to keep the inside of said cell (1) at a pressure higher that that of the surrounding environment until a new sample has been introduced into the cell, thus accomplishing a “washing” of cell for eliminating polluting solvents coming from the desorption of a preceding sample and/or solvents present in the surrounding environment.
