  • Title: Determination of captopril in pharmaceutical samples by flow injection analysis.
    Author: Albero MI, Sánchez-Petreño C, García MS, Ródenas V.
    Journal: J Pharm Biomed Anal; 1993 Oct; 11(10):887-91. PubMed ID: 8305591.
    Abstract:
    A flow injection spectrophotometric method for the determination of captopril involving measurement of the absorbance of the captopril complex with palladium(II) in a 0.12 M HCl medium at 400 nm is presented. The calibration graph was linear over the range 2 x 10(-5)-6 x 10(-4) M. The sampling frequency was 90 h-1 with sample injections of 70 microliters. The proposed method was applied to the determination of captopril in pharmaceutical samples.
