CTR1Replacement Column for FixedGas analysis
May 2013
Separation of Oxygen, Nitrogen, Methane, CO and
CO2 has always been difficult since there is no single
columnmaterial which is good for all these
molecules at room temperature or above.
For example In the past, one column vendor
(ALLTECH) sold a “column in a column” called a
CTR1which is shown at right.
This is a large bulky column consisting of an outer
1/4"OD column and an inner 1/8"OD column.
This column is no longermanufactured, or is not
easily available, soSRI offers an equivalent or better
column for the convenience of our customers.
