Part 1. Capillary columns Columns and Traps
Procedure: Installing capillary columns in the PTV inlet and Volatiles Interface
Procedure: Installing capillary columns in the PTV inlet and Volatiles Interface
The column installation procedures for these two inlets are unique to them.
Details are in the PTV and Volatiles Interface chapters of the Inlets volume.
Procedure: Installing capillary columns in NPD and FID detectors
Be sure you have the correct jet installed in your detector before installing a
column. Details about choosing and installing detector jets are later in this
chapter.
There are two types of NPD/FID detector fittings:
• Adaptable– for use with both packed and capillary columns
• Capillary optimized– for use with capillary columns only. If your adaptable
fitting does not have a capillary adapter installed, begin with step 1. If you
have a capillary optimized fitting or if the capillary adapter is already
installed in your adaptable fitting, begin with step 5.
Materials required
Both fitting types:
Column nut and ferrule
Column cutter
1/4-inch wrench
Metric ruler
Typewriter correction fluid
For adaptable fitting only:
