Scientific paper

SAM (Sample Analysis at Mars) is an experiment which may be proposed for atmospheric, ground and underground in-situ measurements. One of its main goals is to bring direct or indirect information on the possibility for life to have developed on Mars, and to detect traces of past or present biological activity. A solvent extraction-derivatization method was developed to make refractory molecules analysable (i.e. volatile) and identifiable by GC or/and MS. This method will be completed by pyrolysis and the different gaseous mixtures thus obtained are analysed by GC-MS.
