ABSTRACT:
Electron capture detector for use with an effluent stream from a gas chromatograph includes an ionization chamber and a sample inlet system connected to the ionization chamber wherein the sample inlet system effects uniform fluid mixture of the effluent fluid and a make-up gas prior to entry of the fluid mixture into the ionization chamber. A preferred mixing device includes a column liner having a flow acceleration region wherein a localized reduction in the internal diameter of the liner causes momentary turbulence of the fluid mixture.
