Abstract
An effective method based on capillary electrophoresis (CE) for the determination of netilmicin sulphate in commercial ophthalmic formulations was developed and validated. The use of a polymer-coated capillary and a non-absorbing running buffer permitted the elution of netilmicin in cationic mode at pH 3.0 and with direct UV detection at λ = 195 nm. Since pre-treatment of the samples is not required, this procedure may be straightforwardly applied to the other aminoglycosides provided that their extinction coefficient is not too low.
