Oxygen is the most abundant element
on the earth’s surface and as a gas is indispensable
in respiration. Composing almost 21% of the atmosphere,
oxygen is a colorless, odorless and tasteless gas
which supports combustion. As a liquid at -297ºF,
oxygen is light blue in color and is approximately
14% heavier than water.
Liquid oxygen is classified as
a Type II by the Compressed Gas Association (CGA).
CGA Pamphlet G-4.3, Type II, Grade B and the United
States Pharmacopia (USP) specs are considered standards
for commercial liquid oxygen.
Oxygen
(Units in ppm (v/v) unless show otherwise)
Oxygen is also available in high purity VLSI grade
and ultra high purity ELSI grade (99.9999) liquid
oxygen for customer requiring stringent purity standards.
Keen guarantees commercial grade product delivered
as a liquid meets the commercial CGA specification
listed. Keen does not normally guarantee commercial
grade product delivered as a compressed gas meets
the gaseous specification listed because gas purities
are affected by normal cylinder filling practices
and process procedures which may compromise the
integrity of the product.
