Table 11 Ferrules for the TCD detector
Procedure: Installing capillary columns in the ECD and µ-ECD
Both detectors are shipped with a capillary column adapter installed. If it has
been removed, you must replace it before installing a capillary column.
There are two kinds of adapter liner. The straight liner is a simple tube and is a
light brown color. The indented liner is necked down near one end and is clear.
The µ-ECD requires the indented liner.
Materials required
Capillary column adapter
Fused silica liner, straight or indented (required for µ-ECD)
1/4-inch nut and 1/4-inch graphitized Vespel ferrule
Column nut and ferrule
Column cutter
1/4-inch and 9/16-inch wrenches
1. Remove the adapter cap and check the liner. Replace it if it is broken and
reinstall the cap. If you use an indented liner, the indentation must be at the
cap end of the adapter.
