    This study introduces an automated system for analyzing antibiotic release from ocular inserts using thin-layer chromatography (TLC). The new method enhances quantitative evaluation of antibiotic samples, improving accuracy and efficiency.

    Area of Science:

    • Pharmaceutical Science
    • Analytical Chemistry
    • Chromatography

    Background:

    • Characterizing antibiotic release from ocular inserts traditionally involves laborious manual methods.
    • Existing techniques for thin-layer chromatography (TLC) analysis are time-consuming and prone to error.

    Purpose of the Study:

    • To develop and validate a highly automated data collection and processing system for TLC analysis of antibiotic samples.
    • To improve the efficiency and accuracy of characterizing antibiotic release from ocular inserts.

    Main Methods:

    • An automated system interfaced a Kontes densitometer with a personal computer via a Keithley data acquisition system.
    • Two custom BASIC software programs were developed for chromatogram generation and quantitative data processing.
    • The system utilized peak detection and integration routines for spectral analysis of tylosin tartrate.
