Helium ionization detector

摘要

The invention relates to a helium ionisation detector comprising: a helium supply section (2); an ionisation section (3) through which the helium flows in order to create a plasma; a detector body (12) providing a detection zone wherein the plasma meets components to be quantified, the components being eluted from a gas chromatographic separation device (13). According to the invention, the ionisation holder and/or the detector body are designed in such a way that the detection zone is predetermined and restricted. <IMAGE>
