Vaporizing Chamber Interface

For the transfer of water-containing eluents or LC fractions containing amounts of nonevaporating material disturbing on-column introduction, a vaporizing chamber is inserted between the on-column injector and the pre-column system (Figure 5). It consists of a packed liner of 1-2 mm i.d. and is thermostatted at a high temperature (around 300°C) in order to supply the large amount of heat consumed by solvent evaporation. Vapours are discharged by a carrier gas stream through the vapour exit. An uncoated pre-column is used for partial solvent recondensation if solvent trapping is required, but is of no utility for nonwetting water-containing eluents.
