10.2 Column Conditioning
Over time, small amounts of contaminants may accumulate in the analytical column
causing ghost peaks, peak tailing, and/or retention time shifts. Column temperature
programmed methods can be optimized to flush contaminants and high boiling point
compounds with each run, however, a column bakeout may occasionally still be
needed. A bakeout should be performed:
• after the initial installation
• after installing a replacement GC module
• after Micro GC Fusion has been powered off or stored for an extended period of
time
• after Micro GC Fusion has been stored in a shipping case for an extended period
of time
• periodically as needed to refresh column performance
10.2.1 Bakeout from System Status
Perform the following steps to implement a bakeout on Micro GC Fusion. Depending
on the column type, bakeout temperatures will be set according to the isothermal
temperatures indicated in Create a Custom Bakeout Method [}253].

, followed by the icon.
3
Type a bakeout duration in minutes. The bakeout duration should be within the
isothermal temperature duration described in Create a Custom Bakeout Method
[}253].
4
Click the icon to begin the bakeout operation.
CAUTION
Carrier gas must be on (flowing) during a bakeout to avoid damaging
Micro GC Fusion.
