Abstract

Detector has a metal wire running, pref on closed path below outlet of chromatographic column, passing through an oven to evaporate solvent from eluate, then into a flame ionisation detector. During passage through the detector the wire is cleaned and product on wire pyrolysed and detected. Pref. wire has a large diameter splice at its join which produces a high intensity signal on passage through detector.
