| Popis: | Summary An analysis is presented of the reasons for various changes in the response of the flame ionization detector with respect to electrode geometry and molecular structure of sample species. The electrode geometry affects the distribution of the electric field at the base of the flame, where ionization and charge separation are believed to occur, and also affects the incidence of space charge effects on the electric field. The hypothesis is put forward that one-step oxidation of carbon atoms to CO2 is essential in ion formation, and that molecular geometry affects the probability of this occurring. |
