10. The Thermo Scientific gas purification kit contains a high capacity oxygen trap that
should be placed in the nitrogen line. Be sure to purge the regulator and gas line before
attaching the oxygen filter.
11. Keep nitrogen flowing through the trap while attaching the filter to the back of the GC in
order to prevent oxygen from entering the trap.
12. Adjust the pressure regulator to supply a pressure sufficient for the analytical method in
use. In general, 75 psig (517 kPa; 5.17 bar) is more than sufficient for most applications.
Very small bore capillaries may require higher pressures.
The Instant Connect Helium Saver Injector Module is designed to be used with Silflow™
metallic ferrules. This allows for very accurate trimming of the column following compression
of the ferrule onto the column. It is important that only 5 mm of column protrudes past the
tip of the ferrule for proper operation. The inlet has been designed to work optimally with
0.25 mm i.d. columns, although larger (up to 0.32 mm i.d.) or smaller i.d. can be used
successfully.
 To install the column
1. Insert the column through the SilFlow™ nut and ferrule as shown in
Figure 488. Installing the Column Nut and Ferrule
2. Allow a few centimeters of column to extend past the tip of the ferrule and insert it into
the base of the inlet. It will be necessary to gently poke around in order to find the small
bore cone that serves as a column guide and ferrule seat.
3. Use the knurled tool to tighten the nut by finger force only, until the ferrule grabs the
column, and the column no longer slides in the bore of the ferrule.
The column connection should appear as shown in
