We propose to use the unmatched sensitivity of the IRS spectrograph of Spitzer to measure the abundances of key atoms found in young molecular outflows. The Mid-IR window contains the fine structure lines of SI, SiII, NeII and FeI which are fundamental to understand the Sulphur and the Silicon chemistry in shocks and to establish the presence of J-type shocks and their radiative precursors. The detection of large abundance of Sulphur in the very young molecular outflows where the shock precursors have been recently detected will clearly show that atomic Sulphur is ejected from the grains and drives the very rich sulphur chemistry observed in outflows. We stress that IRS onboard of Spitzer is the only instrument capable of detecting the key atoms to understand the nature of the shocks (C- and J-types) and the shock chemistry in molecular outflows.
