Abstract:
1. A head space sampling device for sampling a gas sample from a head space of a vial using a pressurization gas, said head space sampling device comprising: a pressurization gas conduit configured to be in fluid communication with said vial, said pressurization gas conduit comprising: an inlet for receiving said pressurization gas; and a valve for controlling flow of gas therethrough said pressurization gas conduit; a flow sensor for measuring gas flow through said pressurization gas conduit, said flow sensor generating a flow signal indicative of said gas flow; a pressure sensor for measuring gas pressure within said pressurization gas conduit, said pressure sensor generating a pressure signal indicative of said gas pressure; and a controller adapted to receive said flow signal from said flow sensor and said pressure signal from said pressure sensor, said controller being in communication with and controlling said valve of said pressurization gas conduit by opening and closing said valve to selectively control either of said flow through said pressurization gas conduit or said pressure within said pressurization gas conduit.
