HPLC method for polysulphides

Hello,

I need to develop an HPLC method for sodium polysulfides Na2Sx, with x ranging from 1 to 12.

The sample is dissolved in ethanol.

My initial thought was to try an ion pair method with a pH as high as the column can tolerate (to avoid loss of the lower hydrogen sulfides)

Detection should be possible in the lower UV.

What is the opinion of the community?
