摘要： A process and apparatus for detecting small gas leaks in filled, pressurized containers. Each container to be tested, or that portion of each container to be tested, is enclosed and sealed in a test chamber. The space within the test chamber is evacuated to remove any residual gas or liquid within the chamber or on the surfaces of the container. Thereafter, the evacuated chamber is sealed and held for a predetermined period of time to permit any gas leaking from the container to accumulate and diffuse throughout the chamber. A quantity of carrier gas is then introduced into the test chamber and held therein for a predetermined period of time so that the carrier gas and leakage gas may co-mingle and equilibrate. This provides an equilibrated, fixed volume of carrier gas-leakage gas mixture, the leakage gas content of which is dependent only upon the leak rate of the container. The equilibrated mixture is then transferred to a sensor. The signal produced by the sensor for each container tested is compared to the sensor's response to a predetermined leak standard of acceptable value. A method is also provided to compensate for contamination of the carrier gas and for drift of the sensor.

摘要： A device for determining existence of a gas component inside a space of a glass unit includes detecting unit and calibration units. The detecting unit includes laser beam emitting elements emitting laser beam towards the space and detecting elements for detecting reflections of emitted laser beams. The calibration unit includes a calibration chamber having the same gas component as inside the space, and a reflector. The laser beam emitting and detecting elements are arranged to emit and receive beams at an angle so that the focus of the laser spot locates between the laser emitting and detecting elements and outside the line connecting them at the same position in relation to the detecting unit during the measuring process. The detecting and calibration units are movable in relation to each other for calibration purpose so that the laser beam travels through the chamber and the focus spot hits the reflector.

摘要： In order to functionally test a leak detector (20) that comprises a partial pressure sensor (21), a testing device (30) having a variable volume (33) is connected to the leak detector. Said testing device can be a syringe. By changing the volume (33), the partial pressure of the test gas contained in the ambient air is changed. A test is carried out to check whether the leak detector (20) indicates the change. According to the invention, a vacuum pumping device having mechanical vacuum pumps is not required. The method is suitable for testing vacuum systems that contain a vacuum pumping device that is used in the leak test to generate a required vacuum. The service technician can perform the functional test of the leak detector (20) separately from the system and the vacuum pumping device.
