User Guide
The GC defines all parts of the LTM column module columns as one “composite” column. In
, the In segment, analytical column, and Out segment are all part of a single defined
GC column. By defining each segment of an LTM column, the GC can accurately control
column flow even though the flow may pass through different id column material with differing
film thicknesses and different thermal zones.

GC Composite column parts
•
For LTM Series II column modules, the GC will read primary LTM column dimensions
(length, diameter, film thickness, module/column toroid size) and temperature limits from
the LTM column module.
•
Define the column that connects the GC inlet to the LTM column module as the
In
Segment
.
•
Define the column that connects the detector to the column module as the
Out Segment
.
•
If the column segment connected to the detector passes through a second heated zone,
for example an MS transfer line, define the portion passing through the second zone as
Segment 2
.
