HCL-catalyzed decomposition of DMSO diluent in Headspace

Does anyone have some information on the decomposition of DMSO in the headspace oven? I have some unknown early-eluting peaks; have checked for methanethiol, but need to know what other low MW molecules may result.
Thanks

Besides methanethiol, dimethyl sulfide and dimethyl disulfide are candidates if my memory serves me.

Methanol is another possible candidate?

best wishes,
