    • To check this point, we first tried to use ionic chromatography as the most appropriate technique for the dosage of inorganic residue. Unfortunately, irreproducible degradations of trifluoromethanesulfinate (especially in the sodium series) delivered insignificant results. It turns out that fluorine NMR and especially elemental analysis were the best technical means for the evaluation of the quality of the reagents

    • Although this ozone depleting gas could be easily replaced by iodotrifluoromethane, this procedure is limited to the sodium series due to the unavailability of potassium or cesium dithio-nite
