MORE
INFORMATION |
|
Quadrex
offers a complete range of graphite,
graphite/TL-PolyimideTM, and
graphite-VespelTM ferrules
for capillary column installation which
offer a reliable gas tight seal and are
specifically designed for use in your
GC. Standard 1/16" Ferrules are
available for the most popular GCs such
as HP-5890 and 6890s, Varian, Perkin
Elmer, Shimadzu, Finnegan and others.
Ferrules for 1/8" fittings are also
available. |

INJECTOR PORT LINERS
|
MORE
INFORMATION |
|
All
injection port liners are polysiloxane
deactivated and ready for use (other
deactivation available, inquiry for
details). They are manufactured to
exacting tolerances and come in various
configurations for many popular GCs.
Guaranteed inert for phenols, organic
acids and bases. |

SEPTA
|
MORE
INFORMATION |
|
Advances in GC techniques
can lead to higher injection port
temperatures. At elevated temperatures,
septa can stick to the injection port
hardware or harden causing leaks which
can lead to poor reproducibility. Septa
coring is also a problem which results
in debris entering the injector liner
and possibly even the capillary column
itself. Today’s septa technology
provides outstanding mechanical
properties for repeated manual or
autosampler injections, and chemical
properties which give ideal low bleed
characteristics for elevated temperature
use. |

CARRIER GAS TRAPS AND FILTERS
|
MORE
INFORMATION |
|
Today's GC column systems
rely on the highest purity carrier gases
in order to avoid interference's with
the chromatography. To achieve this it
is important to filter out any
contaminants that may be present in your
compressed gas sources. Individual gas
purifiers are available to filter the
contaminants commonly found in
compressed gas cylinders. All of the
following gas purifiers are produced
using the finest grade of adsorbent
media. The housings are constructed
with strength, durability and simplicity
of design in mind. All traps and
filters are supplied with nickel plated
end fittings in either 1/8" or 1/4"
sizes. |
