Isotachophoretic Analysis of Ophthalmic Drops
IZOTACHOFORETICKÁ ANALÝZA OČNÍCHKAPEK
Metodou kapilární izotachoforézy byly analyzovány účinné složky v očních kapkách Tetrakain 0,5%a Atropin 1%. Byla vypracována metodika, která představuje zjednodušení a zvýšení selektivityv porovnání s titračním stanovením podle ČSL-4. Předúprava vzorků spočívá jen v potřebnémředění demineralizovanou vodou, délka stanovení nepřesahuje deset minut. Metodika byla apliko-vána na sledování stability očních kapek.

Overview
The method of capillary isotachophoresis was employed to analyse the active ingredients in theophthalmic drops Tetrakain 0.5% and Atropin 1%. A method has been worked out which representssimplification and increases selectivity in comparison with titration determination according PhBs 4.The pre-adjustment of samples only consists in necessary dilution with demineralised water, thelength of determination not exceeding ten minutes. The method was applied to the investigation ofstability of eye drops.
Key words:
