Abstract
A CZE method has been developed for the purity testing of sulfonic aci ds. By use of an optimized electrolyte system, short analysis times an d high resolution (R-S = 2-4) can be achieved for inorganic anions and for alkyl sulfonic acids from methane-1- to decane-l-sulfonic acid. B y use of indirect UV detection by-products of different sulfonic acids can be determined at the 2 m level, equivalent to 0.02 %, w/w.
