For each channel a backflush option is available to protect the analysis column from high boiling components. In case of different sample streams or auto-calibration, a stream selection option is available. A sample pump (inside the cabinet) and stop-flow valves can be used for sample transfer and atmospheric sample injection.
For process-industry applications, 4-20 mA analogue outputs are available (in combination with EZChrom datasystem).
Several CompactGC's can be stacked in a cabinet together with other instruments like a vacuum sampling device and a dynamic calibrator
