Hi ALL
Does anyone have a gc method for the determination of DMSO. I am doing a leachable study on my pvc stopper so i am letting the stopper sit in DMSo for an hour and then i want to run it on the gc and determine if their are any impurities but obviously first i need to run the dmso on its own to check ist profile
all help greatly appreciated

On a OV-1301 or OV-17 it will require temperatures of > 175°C ? to elute the DMSO. Carbowax columns will take much longer to elute.

Look at headspace chromatograms on the web and see how late DMSO or DMF elute on those chromatograms.

best wishes,

Rod
