Position valves have from 3 to
20 ports, and can be built with pressure and temperature capabilities to
work as part of virtually any analytical technique or process application.
Switching valves are available with zero dead volume fittings for
1/32", 1/16", 1/8", or 1/4" tubing. Multiposition
stream selection valves select from 4 to 26 streams, with multiple
configurations allowing a variety of stream selection techniques. All of
our valves can be ordered in alloys that will withstand the most hostile
environments. We are continuing the development of our extensive Cheminert®
line of high pressure and low pressure valves.
While valves can be switched manually, a pneumatic or electric actuator
facilitates valve positioning and allows the valves to be automated for
unattended operation. Processes can be controlled by our digital valve
sequence programmer or stream selection module, or by a laboratory
computer via our serial valve interface.
We stock a complete range of sampling loops and tubing in a variety of
materials and pre-cut lengths, and we will custom cut and bend tubing to
meet your specific instrumentation plumbing requirements. Our unique
electroforming process for pure nickel tubing eliminates the scratches,
pits, and voids found inside typical drawn tubing, resulting in a highly
chemically inert tubing with a mirror-like interior surface there’s no
chance of any particle shedding or oxide release. All our tubing is
electrolytically cut, polished, and specially cleaned.
Every product in our fittings line is available in a wide range of sizes
and an assortment of alloys and polymers. The line begins with basic nuts
and ferrules and includes unions, tees, crosses, reducers, and manifolds,
with most available in standard or bulkhead versions. Many of our
fittings, like the external to internal adapters, internal reducers, and
manifold pipe thread adapters, are available nowhere else. But all of our
fittings are unique in that they have been designed for the specific
demands of instrumentation and manufactured with the tight tolerances and
premium quality which the field requires.
Much of this comes together in our trace gas analyzer (TGA). This
instrument uses our valves, actuators, tubing, fittings, and detectors as
part of a system which can detect impurities in the ppb range in
ultra-pure gas streams. Our TGAs have found wide acceptance in the
semiconductor industry and with high purity gas-suppliers, who use them to
monitor the quality of the gas standards you probably use to calibrate
your instruments. |
