What is Calibration Gas Powered By Docstoc
					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.
