Area of Science:

  • Analytical Chemistry
  • Pharmaceutical Manufacturing

Background:

  • Good Manufacturing Practices mandate cleaning validation for drug manufacturing equipment.
  • Common analytical techniques include High-Performance Liquid Chromatography (HPLC), Ultraviolet-Visible spectroscopy (UV/Vis), and Total Organic Carbon (TOC) analysis.
  • Specific methods (HPLC, UV/Vis) require individual development for each active substance, which is time-consuming.

Purpose of the Study:

  • To demonstrate the development and validation of a Total Organic Carbon (TOC) method for cleaning validation applications.
  • To highlight TOC as a potentially universal and efficient analytical technique for equipment cleaning verification.

Main Methods:

  • Development and validation of a Total Organic Carbon (TOC) method.
  • Evaluation of performance parameters including linearity, Method Detection Limit (MDL), Limit of Quantitation (LOQ), accuracy, precision, and swab recovery.

    • Main Results:

    • Total Organic Carbon (TOC) analysis is sensitive to the parts per billion (ppb) range.
    • A single TOC method can potentially be applied across various products, unlike specific methods.
    • The study assesses key performance metrics crucial for method validation.

    Conclusions:

    • Total Organic Carbon (TOC) analysis presents a sensitive, less time-consuming, and more versatile approach for cleaning validation compared to specific analytical techniques.
    • The developed TOC method is suitable for cleaning applications, offering efficiency in pharmaceutical quality control.
