Column Selection for Gas and Light Hydrocarbon
Analysis by Packed Column GC
This bulletin is a reprint of a review article published in the
Journal of Chromatographic Science in September, 1978.
The article presents chromatograms for various combina-
tions of 56 sample gases, illustrating separations which can
be obtained by using selected packed columns. The chro-
matograms show the quality of separation, the packing,
and the conditions used for the analysis. A list of current
Supelco publications offers information about additional,
newer materials that offer improved separations or peak
symmetry for some of these analyses.

The major part of this bulletin is a reprint of a review article, The
Analysis of Gases and Light Hydrocarbons by Gas Chromatography,
which was published in the Journal of Chromatographic Science in
September, 1978. The article presents chromatograms for vari-
ous combinations of 56 sample gases, illustrating separations
which can be obtained by using selected packed columns. The
56 analytes are listed in alphabetical order on page 1 of the
review article, accompanied by the number of the chromato-
gram or chromatograms showing the separation. The chromato-
gram shows the quality of separation, the packing, and the
conditions used for the analysis. To select a packing for your
application:
1 Locate on page 1 of the review article the gas or gases you
want to analyze.
2 Refer to the chromatogram(s) listed for the analyte(s).
3 Locate the required packing and/or column in the alphabeti-
cal listing of column packings and columns which follows.
This table presents the information required to order the
required packings and columns.
Because we often get inquiries about these packings, we
continue to make this bulletin available. Some of the packings
listed in the review article are no longer available, however,
and some can be replaced by newer materials that offer
improvements in separations or peak symmetry. Consult the
list of current Supelco publications on the back page of this
bulletin for information about our most recently-developed
packings and columns.
Listing of Column Packings and Columns
The table that follows is an alphabetical listing of the columns
and packings used to produce the chromatograms in the review
article. For easy reference, each entry includes reference to the
chromatogram(s) produced by the column. Entries accompa-
nied by a catalog number currently are in stock at Supelco;
ordering by this number provides faster delivery to you. If the
packing you need does not have a catalog number, but is
available as a custom product, simply order it by the description
in the table.
To order a column for your instrument, refer to the back page of
this publication. Please note that we have in stock empty glass
columns for almost any packed column chromatograph cur-
rently in use. These stock columns are listed in our catalog. If you
do not already have a copy of our most recent catalog, free
copies are available upon request.

2Chromosorb W AW substituted for Inerton.
3Porapak Q substituted for Phasepak Q, which is not commercially available.
4Both 2mm and 4mm ID glass columns are 1/4" OD.
5Outside diameters of stainless steel columns are listed in inches. Where a chromatogram gives OD in metric units, we have converted the value to inches.
660/80 mesh Chromosil 310 and Carbopack B/1% SP-1000 have been substituted for 80/100 mesh materials (80/100 materials not available).
7In the review article, the packing for chromatogram is incorrectly listed as containing 1% XE-60 and 1.5% H
3PO4. The description should be 1.5% XE-60/1% H3PO4
The packing listed in the table (Cat. No. 1-1828) is the correct packing for chromatogram 45.
8Supelpak™ S is our equivalent.

BULLETIN 786
The Definitive Guide to Packed Column GC
Custom Columns
When ordering a custom column refer to our catalog, or call our
sales department. Information we will need to prepare your
column is: instrument manufacturer and model number, column
length and diameter, tubing material, stationary phase and %
coating, and support name, mesh, and treatment. Before you
order your column, be sure to check our catalog. Glass columns
for many instruments are available as stocked items, either empty
or packed. You save time and money when you buy stocked
items. If you select a stocked glass column, simply indicate the
catalog number of the empty glass column and the catalog
number or description of the packing to be used.
Current Literature on Packed Column Analyses
of Gases
The following publications describe analyses on packings/col-
umns developed since 1978, or give much additional informa-
tion not presented in the review article. These publications are
free on request.
Bulletin 722 – Analyses of Sulfur Gases at Trace and Low Percent
Levels, Using Packed Column GC
Bulletin 743 – Separation of Hydrocarbons by Packed Column GC
Bulletin 769 – Monitoring Airborne Contaminants in Workplace
Atmospheres, Using Sampling Devices and GC or HPLC
Bulletin 802 – SP-1700 GC Column Provides Reproducible
Hydrocarbon Analyses
Bulletin 815 – Separating Unsaturated C4 and C5 Hydrocarbons
Bulletin 850 – Simultaneously Monitor Saturated and Unsaturated
C2-C6 Hydrocarbons in Air Samples
Application Note 10 – Efficient Analyses of Permanent Gases, Light
Hydrocarbons, and Light Polar Compounds by GSC
(Describes Carboxen™-1000, a replacement packing
material for Carbosieve packings)
Publication 97982 – HayeSep Porous Polymers
(HayeSep® polymers are modern, efficient replacements
for many of the packings listed in this bulletin)
In addition to these publications, our general catalog is an
excellent source of information about packed column GC.
Included in our current catalog are micropacked columns (1/16"
OD x 0.75mm ID) packed with Carboxen, HayeSep, Molecular
Sieve 5A, and other packings for gas analyses. Also described are
carbon layer open tubular (CLOT), support-coated open tubular
(SCOT) and porous layer open tubular (PLOT) capillary columns,
many of which are well suited to analyses of light hydrocarbons
and other gases.
Packed Column
Application
Guide
895-0005
Our Packed Column Application Guide (Bulletin 890) contains 96
pages of applications incorporating packed column GC: environ-
mental analyses, foods and beverages, clinical applications, and
others. Some of these chromatograms have not yet appeared in
any other Supelco literature. Like our other literature, the guide
is free on request.
