Dear Colleague - yes, it is possible to use ECD for S-containing compounds.  Please see this 1979 article in Journal of Chromatography. It all depends on the sensitivity.

"Electron capture detection of sulphur gases in carbon dioxide at the parts-per-billion level' by M.E. Pic, Volume 171, 1 April 1979, Pages 305-312,

Flame photometric detector (FPD) and pulsed flame photometric detector (PFPD) work very well for sulfur (and phosphor) organic compounds separated on a GC.    

Good luck with your research,

Dear Uwem Bassey,

Yes, you can use Electron capture detection "ECD" and  Flame photometric detector" FPD" as detectors for identifying  sulphur compounds.

Please, find in attach, TECHNICAL GUIDE on Analysis of Halogenated Environmental

Pollutants Using Electron Capture Detection.

Best wishes

In the past (Lovelock 1974) SF6 was used as the standard molecules to check the detector responses, including ECD. So ECD is sensitive to sulphur, but other detectors, such as FPD, are more selective (and on the consequence more sensitive)
