    A new analytical sampling system was developed to detect trace organic compounds in breath. This system enhances analyte concentration and reduces external contamination for accurate breath analysis.

    Area of Science:

    • Analytical Chemistry
    • Biomedical Engineering
    • Environmental Science

    Background:

    • Breath analysis is a non-invasive method for detecting biomarkers.
    • Accurate detection of trace organic components in breath is challenging due to low concentrations and potential contamination.
    • Existing sampling methods may not sufficiently concentrate analytes or prevent interference.

    Purpose of the Study:

    • To develop and present an advanced analytical sampling system for trace organic components in human breath.
    • To optimize the system for maximizing analyte concentrations.
    • To minimize interference from exogenous contamination during sample collection.

    Main Methods:

    • Design and construction of a novel analytical sampling system.
    • System operation protocols focused on efficient analyte capture.
