    Abstract

    A multielement evolved gas analysis technique for the simultaneous determination of up to eight elements is described. The results obtained in one analysis are a quantitative composition in terms of the elements carbon (C), hydrogen (H), nitrogen (N), sulfur (S), chlorine (Cl), bromine (Br), iodine (I) and fluorine (F), and a distribution of these elements as a function of the evolution temperature. Determinations for which the system is used include the amount, composition and volatility of, for instance, kerogen materials, the amount of fixed carbon (coke) on catalysts, or the thermal stability of polymers. The instrument has become an indispensable tool in the screening of materials, in compositional analysis, and in kinetic studies.
