Gas purifying systems
Gas chromatography, environment
analysis, pharmaceutical andbiotechnical applications
Oxygen, moisture and hydrocarbons are
the three main chemical impurities which
have to be reduced before the gases are
used for analytical purposes. Moisture
and oxygen carrier gas limit the life span
of the GC chambers, while hydrocarbons
cause ghost peaks in chromatogram.
This leads to poor results and inadequate
reproducibility.
Semiconductor technology
In the semiconductor industry, oxygen
and carbon are spurious substances in
the construction of the individual layers
which impair the electrical charateristics
of the components. Both these elements
from chemical compounds with virtually
all other substances and are therefore
contaminate the semiconductor layers.
Welding technology
The reduction of oxygen and moisture inwelding gas lead to
narrower more
stable WIG arc and a steadier MIG arc
which causes less splashing. This in turn
produces smoother, narrower seams and
better flow ing of the filler material on
the seam flanks. The fusion penetration
is more intensive and there is less
tendency to form pores. In addition,
cost advantages result from the in-
creased welding speed and reduction is
finishing work.
Excimer-Laser technology
Excimer lasers operate with radiation in
the ultra-violet spectrum. Through gas
discharges, stimulated inert-gas and
halogen compounds (excimers) are
formed, which disintegrate into their
original elements after transmission of
the UV laser beam. Any impurities
which inhibit the electrical stimulation
or which react chemically with the
halogens (fluorine or hydrogen chloride)tend to disrupt the
process. These are
primarily moisture and hydrocarbons.
