Webelectron capture detector . is based on the attenuation by analyte molecules of a standing ion current generated in the effluent by ionization of mobile phase molecules with a β emitter. Electronegative functional groups are particularly effective at capturing electrons and reducing the ion current. (e) The . flame photometric detector WebThe pulsed flame photometric detector (PFPD) is a relatively new weapon in the arsenal of the analytical chemist. Though it uses a flame like its namesake, the flame photometric detector or FPD invented over 30 years ago, the PFPD is a significant improvement because it can provide better sensitivity and selectivity for sulfur and phosphorus.
