Abstract

A device is described wherein the solvent is removed from the liquid chromatographic eluent, prior to immobilising the solute onto a moving, oxidised, titanium tape. The latter is wetted by all solvents, including water. The tape then moves the solute remaining into a pyrolysis zone, integral with a GC detector. For high sensitivity universal operation, a modified Argon lonisation detector has been constructed. Gaseous pyrolysis products are swept into the detector. An alternative design has also been developed comprising a dual Argon lonisation/Electron capture detector for high sensitivity in both universal and selective modes.
