Determining the TCD Electronic Pressure Control (EPC)
If you have a 6890A or 6890A Plus GC, you may have an older design EPC Flow manifold
for the TCD. The older design requires removal of sheet metal panels to attached the TCD
reference flow gas supply inside the GC. The new "Minifold" design allows TCD reference
gas to be connected directly to the back of the GC. Replacement TCD filament block
assemblies have different part numbers depending on the EPC design type.
Once you have determined the type of EPC module, decide whether to order a passivated
filament block assembly. The passivated assembly is recommended for fatty acid analysis
or reactive/acidic samples.
