The finest Fused Silica Columns from Chromatography Associates
Chromatography Associates Inc. was founded to
manufacture and deliver the finest GC Capillary Columns
and Accessories possible.
CA capillaries are crosslinked and surface bonded yielding
solvent rinseable, low bleed, high performance columns.
Proprietary high temperature deactivation techniques ensure
the inertness needed for today’s demanding analyses.
All CA columns are individually tested to ensure proper
performance. Capillary columns are somewhat like children
who have the same parents and upbringing but yet always
come out different. Experience has shown us that columns
made from the same lot of tubing, the same deactivant and
phase solutions, bonded and conditioned using the same
equipment come out different. Like caring for children we
carefully manufacture each column and monitor them along
each step of production and testing. This benefits both you
and us. You get consistent high performance columns and
we get fewer failures.
Column testing should be performed both isothermally and
programmed. Isothermal testing is performed first to
accurately assess efficiency and inertness. Temperature
programming during this phase of the testing does not yield
the familiar theoretical plate counts and may hide/obscure
inertness problems by artificially sharpening the peaks. Once
this testing is complete the columns should be programmed
up in temperature to assess the bleed levels.
CA capillary columns are prerinsed to ensure the
completeness of the crosslinking and surface bonding.
Please take the opportunity to read the Installation Manual
that comes with each column. It contains vital information to
ensure proper efficiency, inertness and low bleed from your
new CA column.
Who We Are
Chromatography Associates, Inc. is a group of dedicated
chromatographers who manufacture premium capillary
columns at fair prices. We have advanced the art of column
manufacturing which means longer column life for you.
Why We Care
We’re chromatographers working for chromatographers: no
fancy gimmicks, gadgets or merchandise. We work for the
technical person or technical buyer who wants expert help
purchasing the perfect, long lasting column. We know you
don’t have any time to waste!
What Makes Us Different
Our capillary Columns: It’s what we do - it’s all we do. We’ve
pioneered new technologies in column manufacturing. Each
hand made, individually tested column will be the longest
lasting, most efficient, most inert, and lowest bleed column
available anywhere.
