Abstract
Flow modulation of methane-doped carrier gas is used to visualize the second dimension hold-up time in GCÂ ÃÂ GC continuously throughout the run. This provides an internal reference of hold-up time and presents a straightforward means of examining retention in each dimension of GCÂ ÃÂ GC. Retention factors on similar and dissimilar column pairs are examined. Stationary phase bleed is shown to be retained by the second dimension column.
