    This study introduces a new method for amino acid analysis in mouse tissues that handles noisy data and variable retention times. This approach improves substance identification in complex physiological samples.

    Area of Science:

    • Biochemistry
    • Analytical Chemistry
    • Chromatography

    Background:

    • Traditional chromatographic analysis methods rely on consistent retention times for accurate peak identification.
    • Analyzing physiological fluids often presents challenges due to noisy data and shifting baselines.
    • Existing methods struggle with misidentification of substances in complex biological samples.

    Purpose of the Study:

    • To develop a robust method for amino acid analysis in physiological mouse tissues.
    • To overcome limitations of conventional chromatographic techniques in handling complex biological samples.
    • To improve the accuracy of substance identification despite variable experimental conditions.

    Main Methods:

    • Development of a novel computational approach for chromatogram analysis.
