SRI GC Columns


Packed and capillary columns for your specific GC application




SRI Instruments can supply a wide range
of packed and wide-bore capillary columns
for use in our GC systems



SRI Instruments offers the following choices in packed
and capillary columns, for our line of gas chromatographs.
They are described briefly as follows:

PACKED COLUMNS

This column is packed in a 3' x 1/8" O.D. stainless steel coil
and is ideal for the separation of natural gas, C1 through C6,
and some volatile compounds.  A good general purpose
and educational column, it is priced at $100.  The part number
for this column is 8600-PKC1.
This column is typically packed in a 3' x 1/8" section of Teflon®
tubing, and is indicated for the separation of sulfurous compounds.
The Teflon® tubing is used instead of stainless steel, as sulfurous
compounds could be adsorbed by the metal column, affect analyses.
The price for this column is $150.  The part number is 8600-PKC3 .
This column is a specialized selection that is really
a column-within-a-column.  One packed column cohabitates
within a second, outer packed column, utilizing two completely
different packing materials (silica gel and molecular sieve 5A)
to obtain two completely different analyses within the same chromatogram.
This enables the user to obtain both the fixed gas analyses and
separation of CO2, oxygen, and other gases simultaneously.  This column
may be ordered coiled in either a normal diameter for use with our 8610C GC,
or in a small diameter for use with our smaller column oven-equipped 310 GC.
The price is $300, and the part number is 8600-PKC4.
This column is packed in a 24' x 1/8" stainless steel coil,
and is indicated for the separation of CFC's and HCFC's.
It is ideal for refrigerant reclamation and QC analyses.
The price for this column is $395.  The part number is 8600-PKC4 .

CAPILLARY COLUMNS

We offer a DB-1 type thick film wide-bore capillary column,
ideal for BTEX, GRO-DRO, and other general analyses,
in a 5 micron film thickness, in column lengths of
15M, 30M, and 60M.  Pricing is listed below.
We offer a DB-5 type thin film wide-bore capillary column,
ideal for semi-volatiles, PCB's, pesticides, and other analyses,
in a 1.0 micron film thickness, in column lengths of 15M, 30M,
and 60M.  Pricing is listed below.
We also offer a volatiles type wide-bore capillary column,
indicated for dichlorodifluoromethane, chloromethane, vinyl chloride,
and other light volatile analyses, in column lengths of 15M, 30M,
and 60M.  Pricing is listed below.

15M Wide Bore Capillary Column, 0.53mm I.D.    8600-WBC1    $250
30M Wide Bore Capillary Column, 0.53mm I.D.    8600-WBC2    $500
60M Wide Bore Capillary Column, 0.53mm I.D.    8600-WBC3    $875

When ordering any of the above capillary columns, please specify the stationary phase desired.
