Design considerations for pulsed-flow comprehensive two-dimensional GC: Dynamic flow model approach
A dynamic flow model, which maps carrier gas pressures and carrier gas flow rates through the first dimension separation column, the modulator sample loop, and the second dimension separation column(s) in a pulsed-flow modulation comprehensive two-dimensional gas chromatography (PFM-GCGC) system is...
