Squella Serrano, Juan; Álvarez Lueje, Alejandro; Sturm,; Núñez Vergara, Luis (1993)A differential pulse polarographic method for the identification and quantitative determination of enoxacin is described. The method is based on the electrochemical reduction of the drug at the dropping mercury electrode. ...

Systematic HPLC study of a new series of 4-methyl-1,4-dihydropyridines with antitrombotic activity Núñez Vergara, Luis; Álvarez Lueje, Alejandro; Sturm,; Sunkel,; Squella Serrano, Juan (Marcel Dekker Inc., 1998)A systematic study of a new series of 4-methyl-1,4-dihydropyridine derivatives by HPLC by both photodiode array and electrochemical detectors is reported. The optimum mobile phase was acetonitrile/0.05 M phosphate buffer ...

Sturm,; Canelo,; Núñez Vergara, Luis; Squella Serrano, Juan (Elsevier B.V., 1997)A differential pulse polarographic method for the quantitative determination of ketorolac is described. Ketorolac is an antiinflammatory-analgesic agent that is directly electroreducible at the mercury electrode. The ...
