How to make Selection of Capillary Columns for
Gas Chromatography?
For every compound and chemical industry, there
would be handling of various solids, liquids and
gasses. But what happens is, there might be a few
compounds which would not be in the pure form.
However, in order to get the separation process
and GC process done, there will be need for good
quality capillary columns. So, keep an eye on the
best manufacturers. Since there will be
continuous need for such processes, there will be
need for those items too. Making selection of
these columns is important and heres how you
must go about.

Selection on the basis of phase There are
basically two phases when it comes to compounds.
The first is the stationery phase and the other
is moving phase. When you choose the columns, you
will have to keep in mind that which phase, it is
going to be. For capillary ones, generally there
will be need for stationery phase. Thus, while
taking up GC, you will have to decide that how
the use of gas chromatography column needs to be
applied. Selection on the basis of ID In the
columns what matters the most are the dimensions
inside. Thus, as per the need of the process and
the industry, there can be custom solutions.

The industry should order the columns or select
them on the basis of their capacities. Ideally
those with 0.25mm are quite popular. Selection
on the basis of film thickness Since there would
be different processes, it is vital to understand
that how they are to be operated. There would be
certain film thickness which might work for one
process and there might be some which might work
for the other. So, all you must do is, find out
the exact process and hence then decide what will
be the relevant film thickness that capillary
columns should ideally have.

Selection on the basis of column length The most
popular gas chromatography column is a 30 meter
one. So, all you must do is find out, if this is
the one suitable for your industry. But there are
others that would come in 15 meters and 60 meters
too. The length of the columns would affect the
gas chromatography process and hence what matters
the most is how you select the products. Selectio
n on the basis of compounds There would be many
different compounds in different states. So,
based on the need you will have to decide which
are the columns to be used? Apart from the
columns, there will be need for other accessories
like column connectors too.
5
Selection on the basis of quality It is
important to choose the columns on the basis of
material and quality. Find the relevant and
reputed company that deals in such items. There
would be many companies that would deal in these.
You must settle down for the one whose reviews
you get as the best ones online. In fact, if you
have been an old company which deals in compounds
then there will be continuous need for these
tools too.
