  • Title: Application of MEKC for determination of ticarcillin and clavulanic acid in Timentin intravenous preparation.
    Author: Pajchel G, Tyski S.
    Journal: J Pharm Biomed Anal; 2003 Apr 24; 32(1):59-69. PubMed ID: 12852449.
    Abstract:
    A micellar electrokinetic chromatography method for simultaneous assay of ticarcillin and clavulanic acid in Timentin i.v. injection preparation was developed. This method ensures excellent separation of both components of Timentin preparation. The validation of the method was performed, and specificity, reproducibility, precision and accuracy were confirmed. The detection and quantitative limits for Timentin were established in the concentrations 0.04 and 0.08 mg/ml, respectively. The elaborated technique was compared with two methods routinely used-UV and high performance liquid chromatography (HPLC). The obtained results and their statistical analysis proved the same precision of all methods, however, no significant differences were observed between CE and HPLC.
