Abstract:

During the preparative gas chromatography of some organophosphorus esters using a silicone gum rubber column, a copious white deposit was formed on the collector electrode of the flame ionization detector over a period of 2 weeks. Although the deposits from both detector and injection port appeared similar to the naked eye, analysis by the Debye-Scherrer X-ray diffraction method and by optical emission spectroscopic techniques showed that the detector deposits were mainly silicon phosphate 2SiO2.P2O5, and the injection port samples were alpha cristobalite SiO2.
