 To connect backflush line, precolumn, and analytical capillary column
CAUTION Before starting make sure the Gas Sampling Valve (GSV) module is correctly
installed into its seat.
ATTENTION Avant de commencer, vérifiez que le module à vanne d'échantillonnage de
gaz (GSV) est bien installé dans son logement.
The result of this operation is schematically shown in the example of
Figure 372. Connecting GSV Backflush Line, Precolumn, and Analytical Capillary Column
Note Could be necessary to adjust the position of the three-way connector when installing
backflush line, precolumn, and capillary column to stress as minimal as possible.
When the GSV module is inserted into its position on the upper deck of the GC, the
backflush line metal tubing protrudes into the GC oven.
1. Open the front door of the GC.
2. Remove nut and ferrule from the metal tubing of the GSV nodule.
3. Connect the backflush line metal tubing coming from the bottom of the Gas Sampling
Valve module to the three-way connector.
a. Slide the 1/32-in. nut and the Vespel/Graphite ferrule PN 29003428 onto the end of
the backflush line with the beveled end facing towards the three-way connector.
b. Insert the backflush line into the central position of the three-way connector.
c. Slide the retaining nut onto the backflush line through its side cut.
d. Use the 5 mm wrench to tighten the retaining nut. Use enough pressure necessary to
obtain a good seal without overtighten.
4. Connect the precolumn to the Tee connector.
a. Place the precolumn on the column support.
