ABSTRACT:
Dimensionally optimized flame ionization detector for use in chromatography in which positive ions are caused to be collected by applying positive potential to flame tip. It has been discovered that there exists optimum dimensions of the collector electrode and the spacing between collector electrode and flame tip to resist glassing and corrosion without diminishing other operating parameters. The collector electrode inside diameter is in the range of 0.114 inch to 0.3 inch and the flame tip to collector electrode is in range from 1 mm to 3 mm.
