Installing LTM Columns

Overview

The LTM section of the 5975T LTM GC/MSD consists of a heated LTM column
module and two guard columns that connect the LTM to the split/splitless inlet
and MSD transfer line. These guard columns help limit contamination in the
LTM, and the MSD.
The sample flows through the inlet, into the first guard column (inlet guard
column) into the LTM, then through the second guard column (MSD guard
column) into the MSD transfer line to the MSD. See
