Hydrogen
Hydrogen
makes up 98% of the known universe, and it is the third most abundant
element on the earth's surface. It is a component of
water, minerals and acids, and it makes up a fundamental part of
all hydrocarbons and organic substances. At atmospheric temperatures
and pressures, hydrogen exists as a gas; however, it liquefies
at -252.9°C (-423°F). Next to helium, it is the coldest
known fluid.
Hydrogen is one of the materials now being considered
as an alternative fuel because it is renewable, abundant, efficient,
and unlike other
alternatives, produces zero emissions. Many believe that this
versatile material will become a primary fuel and energy carrier
of the future. |

Fuel Cells
Hydrogen can produce electricity and electricity can produce hydrogen,
creating an energy loop that is renewable and harmless to the environment.
Hydrogen combines chemically with most elements, so it has been
utilized as an industrial chemical in a wide range of applications
for many years. In vehicles, hydrogen can be used as a fuel in
two ways: to produce electricity in a fuel cell for the cleanest
option; or in an internal combustion engine where emissions are
still significantly reduced compared with other fuels. The reforming
of natural gas by applying heat is currently the most economical
process for producing hydrogen. |

Hydrogen Generation Certification for the laboratory
Electrolysis produces hydrogen by using an electrical current to
separate water into hydrogen and oxygen. Analytically, it is not
the purity of the gas that will guarantee error free laboratory
analyses, but the maximum level of impurities that makes the difference.
The importance of impurity levels depend on the function of the
gas, the sensitivity of the analysis and on the specific detector
used. One should select a GC gas and grade most appropriate to
your specific analysis i.e. not containing impurities which would
affect your analysis or degrade your chromatographic equipment,
and have it certified. |
