3000 Micro GC Operating Manual
8.2 Remove and Replace a 3000 Micro GC Module
The following procedure will outline the steps necessary to fully remove and
replace a module.
8.2.1 Types of Replacement Modules
In general, any type of GC module can be replaced with one of a different type. This
includes modules with different columns, columns lengths, and injectors.
NOTE: Installing a GC module in a previously unused channel is not supported.
8.2.2 Performance Enhanced GC Module vs. Standard GC Module
There are two types of GC modules.
 Standard GC module: This module type must be decommissioned and given
a new address via the embedded web page. The serial number can be
identified by the label on the top of the module.
A PN beginning with G2801 identifies a standard module.
 Performance Enhanced GC module: This module type contains a dual inline
package (DIP) switch that can be set for a specific module address. This
eliminates the need to decommission a GC module first, so the GC module can
be easily replaced. The serial number can be identified by the label on the top
of the module.
A PN beginning with G2807 identifies a Performance Enhanced module.
Features of the performance enhanced GC module:
 Peaks return to the baseline faster for better separation
 Better sensitivity
 Easier to integrate low ppm peaks
 DIP switch for convenience when replacing GC modules
NOTE: Performance Enhanced GC modules do not have to be
decommissioned or recommissioned. Section 8.2.4, Decommission a
Standard GC Module, on page 8-7 and section 8.2.7, Commission a
New Standard GC Module, on page 8-20 do not apply when replacing
a Performance Enhanced module.
