摘要： A method for providing a calibration test gas sample includes identifying a first test canister containing a standard test gas including an ionic gas. A chemical formulation of the standard test gas includes a cation and an anion. The method further includes replacing the first test canister with a second test canister containing an improved test gas. A chemical formulation of the improved test gas includes a replacement atom comprising one of a heavier isotope of one of the cation and the anion.

摘要： An improved gas cylinder configured to prevent degradation of a contained pressurized reactive gas includes a metallic gas cylinder configured to store a pressurized reactive gas within the cylinder. The improved gas cylinder further includes a cylinder lining including parylene. In one embodiment, the parylene lined cylinder can be heat treated. The improved gas cylinder prevents cracking of the cylinder lining, thereby preventing the contained reactive gas from coming into contact with the metallic gas cylinder.

摘要： A gas detector is tested by releasing detectable gas from a storage medium and delivering it to the gas detector. A cartridge for delivering detectable gas includes a container with an outlet and a storage medium in the container. Detectable gas is stored in the storage medium for being desorbed from the storage medium. A test device can include a receptacle for receiving the cartridge, an interface for fluidly coupling the device to a gas detector, and passaging to provide fluid communication between the interface and both the cartridge received in the receptacle and external air. A pump can pump external air and the detectable gas released from the cartridge through the passaging and interface such that the pumped detectable gas and air form a proportioned mixture for testing the gas detector.
