Using calibration gas is essential to ensure that your industrial safety procedures are working effectively. These mixtures are used with confined space instruments to test the detector with a known concentration test. Calibration gas should be used after purchasing the instrument, as well as before every safety procedure. Luckily, the calibration process is very quick and easy to complete, making it easy for individuals to check their own devices for optimal performance. Test canisters need to conform to the latest national and worldwide standards to be completely effective in regulating safety devices. These standards use permeation rate data for known compounds and are instrumental in establishing reference points for qualitative analysis. Calibration gas can be used for checking substance detectors, particle analysers, chromatographs, environmental monitors, clinical analysers, breath monitors and smoke alarms. Calibration gas is instrumental in monitoring the health of the environment and checking pollution levels. As environmental monitoring instruments are by necessity quite delicate and sensitive, regular performance checks with a reliable pure compound is a standard procedure when testing air quality and pollution. Besides health and safety applications, pure gas is also widely used in research and development, general laboratory maintenance as well as university teaching and research. It is important that a standard procedure for testing is applied across an industry or area, to ensure accurate and precise results. This procedure should be as simple as possible, and if possible, executed by regular safety officers, to minimise the risk of human error. In the field and in action, calibration gas can be used to give a rough guide to the performance and accuracy of the device in question. In the testing laboratories and controlled situations, however, a highly accurate calibration is required. A wide range of compounds are used to test safety monitoring devices. These include corrosive and toxic substances such as nitric oxide, hydrogen sulphide, sulphur dioxide, hydrogen chloride, chlorine and phosphine. As well as pure concentrates, calibration gases are available as mixtures to check for a full range of different substances. The production of these pure and mixed forms of test compounds involves a highly complex process which includes consideration of the raw chemical material, impurity analysis, precise diffusion and a final independent analysis to ensure that the stated concentration is highly accurate. Calibration gas canisters are also filled with the utmost care to ensure there are no opportunities for contamination or leaks. A variety of different canister filling techniques are used, depending on the compound being handled, all of which are engineered to produce a fully accurate final product.
