  • Title: Determination of aspoxicillin in broncho-alveolar lavage fluid by high-performance liquid chromatography with photolysis and electrochemical detection.
    Author: Yamazaki T, Ishikawa T, Nakai H, Miyai M, Tsubota T, Asano K.
    Journal: J Chromatogr; 1993 May 19; 615(1):180-5. PubMed ID: 8340459.
    Abstract:
    A determination method for the penicillin antibiotic aspoxicillin in broncho-alveolar lavage fluid has been developed, involving high-performance liquid chromatography and post-column photolysis. The method enabled the determination of aspoxicillin at concentrations below 100 ng/ml, with a linear calibration curve at concentrations of 1-1000 ng/ml for 100 microliters of lavage fluid. The detection limit was 1 ng/ml at a signal-to-noise ratio of 3:1.
