Curie point pyrolysis gas chromatography using ferromagnetic tubes as sample supports

Summary In pulse-mode pyrolysis gas chromatography, where a solid sample is pyrolysed by contact with a heated filament, there is usually no thermal equilibrium between sample and support. Such an equilibrium is approached by pyrolysing solid samples within ferromagnetic tubes. Tubes 1.5 mm outside diameter (10 % wall) may be heated and stabilized to the Curie Point (iron: 760 °C) in 60 msec. This type of Curie Point pyrolysis will help to increase reproducibility in pyrolysis gas chromatography.In part presented at the Seventh International Symposium on Advances in Chromatography, Las Vegas, Nevada, November 29 / December 3, 1971 and the Second International Symposium on Pyrolysis Gas Chromatography, Paris, September 28/29, 1972
