A novel potentiometric, enantioselective membrane electrode based on graphite paste (graphite powder and paraffin oil), impregnated with 10–3 mol/L 2-hydroxy-3-trimethylammoniopropyl-β-cyclodextrin (as chloride salt) solution, has been constructed. The potentiometric, enantioselective membrane electrode can be used for the reliable assay of S-enalapril as raw material and from its pharmaceutical formulations in the concentration range of 3.6 × 10–5 – 6.4 × 10–2 mol/L, with a detection limit of… CONTINUE READING
