Early solvent vapor exit, injection

Figure 3.9. Schematic diagram of an automated on-line solid-phase extraction-gas chromatography system. Large volume on-column injection with an early solvent vapor exit and retaining precolumn is used for sample transfer. (From ref. [117] Elsevier). Figure 3.9.

Large volume on-column injection with an early solvent vapor exit and retaining precolumn is used for sample transfer. (From ref. [117] Elsevier).
The on-column injection techniques, in which the solvent is generally vaporized in a few meters of uncoated deactivated capillary (retention gap) and vented via an early vapor exit valve, are of good accuracy and reproducibility.A schematic diagram for on-column injection is shown in Fig. 1. The on-column large-volume injection... [Pg.1319]
