15.9 Replacing The Column In The Gas Chromatograph
The gas chromatograph column in the HAPSITE is a 30 m x 0.32 mm column. The
flow through this column has been preset to deliver 3 mL/min flow of nitrogen
through the system. Replacement columns should possess the same dimensions
as the original column to ensure proper function of the HAPSITE. Before replacing
the column with any other dimension, contact INFICON.
Tools/Equipment Required
1/4 inch open end wrench
1/2 inch open end wrench
needle nose pliers
flat head screw driver
#2 Phillips-head screwdriver
Procedure for Replacing the GC Column
1 To replace a column first remove the top yellow cover. Remove the captive
screws and the LEMO connector nut. See Figure 15-50.
Figure 15-50 Removing Yellow Cover
2 Remove the top GC cover as shown in Figure 15-51. This cover serves two
purposes: (1) it keeps the heat in the oven and (2) it holds the column in place.
There is a connector on the bottom of the column module that connects to the
column module board. The column module sits on top of the column module
board connector and the GC cover holds them all in place. Using a flat tip screw
driver, unscrew the two capture screws on top of the oven cover.
