Zusammenfassung

Zum Nachweis anorganischer Chloride bei der Hochtemperatur-Gas-Chromatographie (450–1000°C) wird mit gutem Erfolg ein Leitfähigkeitsdetektor verwendet. Es wird eine 250 mm-Pt-Säule benutzt, gefüllt mit einem geschmolzenen Salz (Alkaki oder Erd-alkalichloride) auf Chromosorb WAW. Als Trägergas dient Helium (60 ml/min). Folgende Gemische können getrennt werden: BeCl2/AlCl3 bei 560°C; PbCl2/SnCl2 bei 780°C; BiCl3/SbCl3 bei 660°C; BiCl3/PbCl2 bei 560°C; TlCl/FeCl3, TlCl/BeCl2, TlCl/AlCl3, ThCl4/AlCl3 bei 640°C; InCl3/(AlCl3 + FeCl3) bei 660°C; ZnCl2/PbCl2 bei 780°C; SnCl2/(NaCl+KCl) bei 830°C; TlCl/PbCl2 bei 830°C.

Summary

Electric-conductivity detector is used successfully for the detection of inorganic chlorides in high temperature gas chromatography (450–1000°C). Following mixtures can be separated by the carrier gas He (60 ml/min) on a 250 mm Pt-column with the packing constructed of a fused salt and Chromosorb WAW: BeCl2/AlCl3at 560°C; PbCl2/SnCl2at 780°C; BiCl3/SbCl3at 660°C; BiCl3/PbCl2 at 560°C; TlCl/FeCl3, TlCl/BeCl2, TlCl/AlCl3, ThCl4/AlCl3 at 640°C; InCl3/(AlCl3+FeCl3) at 660°C; ZnCl2/PbCl2 at 780°C; SnCl2/(NaCl+KCl) at 830°C; and TlCl/PbCl2 at 830°C.
