ABSTRACT The ASVAHL Analytical Group has worked for four years. The main objectives were : 1) To develop straight forward methods suitable for heavy products which allow an effective conversion unit follow-up and a better understanding of the phenomenon involved in. Methods which were studied include global characterizations, elementary and structural analysis. 2) To increase the knowledge of the intimate structure of heavy products. To do that, fundamental research have been done sometimes in collaboration with university laboratories and by the use of a wide range of sophisticated methods (molecular distillation, gas chromatography, mass spectrometry alone or coupled with gas chromatography, 1H, 13C, 33S nuclear magnetic resonance, FT/infra red, EXAFS/XANES, small angle X-ray and neutron scattering). In the same way, the ASVAHL Analytical Group has collected a standard sample bank. It organized an internal symposium dedicated for the characterization of heavy products (Lyon, France, 1984).
