This document introduces the enhanced separation power of GC x GC, which can be combined with selective and non-selective detectors to provide enhanced sample information and confirmation that would otherwise not be possible in a single run.
The document details how the enhanced separation power of GCxGC can be combined with selective and non-selective detectors to provide enhanced sample information and confirmation. It explains that simultaneous multi-detector signal acquisition is possible with constant flow-modulated GCxGC when various Capillary Flow Technology (CFT) devices and carefully sized restrictors are coupled to the second column flow from the modulator.
Hydrogen is the carrier gas used for all experiments.
Column 1 has a maximum flow rate of 0.8 ml/min, while column 2 runs at a constant flow of 22 ml/min.
