A method of purifying dimethyl sulfoxide includes distilling a dimethyl sulfoxide-containing liquid in the presence of sodium carbonate under a reduced pressure in an inert gas atmosphere to distill out dimethyl sulfoxide, an amount of the sodium carbonate with respect to 100 g of pure dimethyl sulfoxide in a residual liquid after the distillation being 6 times or more the amount of the sodium carbonate with respect to 100 g of the pure dimethyl sulfoxide in the dimethyl sulfoxide-containing liquid before the distillation.

Fluorinated fluid conditioning systems are described. In particular, fluorinated fluid conditioning systems including an electrically non-conductive fluorinated fluid and a filter including desensitized activated carbon sorbent are described.
