Abstract

An account is given of the preparation, separation and detection of volatile fluorides. These fluorides are formed by the reaction of chlorine trifluoride with the elements in a specially designed PTFE reaction vessel enclosed in an HF coil. A comparison is also made of a spectroscopic detector with a katharometer for the detection of the fluorides. The separation of volatile fluorides has been reported to be partially successful on perfluorinated materials such as Kel-F oils 1 _3 or waxes on PTFE supports. The present communication describes a more detailed investigation of these separations and also compares the performance of a newly developed spectroscopic 4 detector with a conventional katharometer detector.
