โฆ Synopsis
A system is described consisting of two high-resolution capillary columns of different polarity placed in series. Compounds which are not separated or incompletely separated on the first column can be resolved and characterized on the second column. The system enables the selective transfer of one or more peaks eluted from the first column on to the second column without trapping. For both columns a precision is attained corresponding to a standard deviation less than 0.05 index units for all types of hydrocarbons.
