We use Very High Resolution Mass Spectrometry for analyses of the soluble fraction of yellow stuff produced in laboratory. Their analyses show that they are composed of molecules with high molecular weight (m/z>4000). Fragmentations suggest that grafted molecules constitute a part of them. Hexamethylenetetramine derivatives have also been detected. First results and further analytical developments will be presented to facilitate the understanding of the residue composition and of its chemical evolution. Furthermore, we present for the first time the concept of the VAHIIA project which concerns the analysis of volatiles coming from the heating of interstellar ice analogues.
