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.
摘要翻译：用于检测填充的加压容器中的小气体泄漏的方法和装置。待测试的每个容器或每个要测试的容器的部分被封闭并密封在测试室中。将测试室内的空间抽真空以除去腔室内或容器表面上的残留气体或液体。此后，将真空室密封并保持预定的时间，以允许从容器泄漏的任何气体积聚并扩散到整个室中。然后将一定数量的载气引入试验室并将其保持在预定的时间段内，以使载气和泄漏气体共混并平衡。这提供了平衡的固定体积的载气泄漏气体混合物，其泄漏气体含量仅取决于容器的泄漏率。然后将平衡的混合物转移到传感器。将由传感器产生的每个容器测试的信号与传感器对可接受值的预定泄漏标准的响应进行比较。还提供了一种补偿载气污染和传感器漂移的方法。

摘要： A method for determining correct performance of a sampling pipe in an aspirated particle and/or gas sampling system. The method includes causing a change in airflow n a sampling pipe of the aspirated particle and/or gas sampling system that induces a change in at least one airflow property within the sampling pipe, and detecting an effect of the change in said airflow property. Also disclosed is a method for determining correct performance of an aspirated particle gas sampling system. The method includes determining correct performance of a sampling pipe in the aspirated particle and/or gas sampling and determining correct performance of a detector in the aspirated particle and/or gas sampling system, wherein a test fluid is introduced to the aspirated particle and/or gas sampling system at or near the detector.

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.
