GC - Different Configurations for Packed GC Columns

Created by Dr. Know 22 days ago | Last modified by Dr. Know 22 days ago

There are 3 column configurations for the use of packed columns in 78XX or older systems: A, B and C.

These column configurations are only needed for glass and 1/4-inch stainless steel columns, 1/8-inch Stainless steel columns can easily be bend in every direction, and therefore are shipped in one model (configuration C).

See below the explanation for the older type GC’s (78XX and older.)

Injector Side

Detector Side

Configuration A	Can be used with all detectors except the TCD, no adapter is used on both sides
Configuration B	Can only be used with a TCD. No adapter is needed on the injector side (long leg is mainly for on-column injections). On the detector side you will need G1532-20710 (with 1/8-inch nut and ferrule, 5180-4103 and 0100-1332), but only for 1/4-inch columns, 1/8-inch columns only need a 1/8-inch nut and ferrule (see figure1)
ConfigurationC	Can be used with all detectors, adapters are needed for both injector and detector side, See tables below

Additional Information about 88XX GC’s

Configuration A is not an option for 88XX GC’s, this will not fit.

If the customer so far has been using A configuration columns, they now would need to use a C configuration column.
What they need for this C configuration is the purged packed inlet adapter in combination with a detector adapter for the 88XX GC’s:

G3450-20344, 1/4-inch Packed Column Adapter
G3450-20342, 1/8-inch Packed Column Adapter

The B configuration with a TCD will work the same as with the older models, with the adapters G3450-20344 and G3450-24342.

If the 88XX system is equipped with ECD, then glass columns cannot be used as they do not fit the oven. The solution is to switch to 1/8-inch UltiMetal deactivated packed columns.
