224–200 K), with traces of oxygen and argon, within the
specied limits of noncombustibility, and with particu-
lates less than 1 mm. This quality of nitrogen is generally
useful to enhance safety from combustible products, pre-
vent toxic emissions, improve product quality, and elimi-
nate odors from chemical processes. Its high dryness has
also helped prevent problems associated with moisture
contamination of processed materials. Standard systems
