LECO’s GCxGC Utilizing a Consumable- Free Modulator and Second Column Modulation

Operation of the CFM-equipped GCxGC (in the SCC mode) has been demonstrated to expand the usable range for less volatile species to above the n-C upper limit specified for the LN modulator system. This increase in the upper limit of the usable range requires that the system be configured in the Standard Column Configuration (modulating on the beginning of the second dimension column), instead of the High Volatility Column Configuration (modulating on the end of the first dimension column) specified for quantitative modulation of n-C . The change from HVCC to SCC increases
