Description

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.
