A new immune algorithm effectively resolves and quantifies components in overlapping chromatograms. This computational method offers a faster and satisfactory alternative to traditional techniques for chromatographic data analysis.

Area of Science:

  • Analytical Chemistry
  • Computational Chemistry
  • Biomimetic Computing

Background:

  • Overlapping chromatograms present significant challenges in component resolution and accurate quantification.
  • Existing methods like the conventional least-square method can be computationally intensive and may lack precision.

Purpose of the Study:

  • To introduce a novel immune algorithm inspired by biological immune systems for analyzing overlapping chromatograms.
  • To evaluate the algorithm's performance in resolving and quantitatively determining components in complex chromatographic data.

Main Methods:

  • The proposed immune algorithm iteratively subtracts standard sample chromatograms from the input overlapping chromatogram.
  • A network-based iterative subtraction approach is employed until the residual stabilizes, indicating convergence.

Related Experiment Videos

  • The method was validated using both simulated and experimental chromatographic datasets.

    • Main Results:

    • The immune algorithm successfully resolved components within overlapping chromatograms.
    • Quantitative determination of components showed satisfactory recovery rates.
    • The algorithm demonstrated a significantly faster calculation speed compared to the conventional least-square method.

    Conclusions:

    • The novel immune algorithm provides an efficient and accurate solution for the resolution and quantitative determination of components in overlapping chromatograms.
    • This biomimetic approach offers a promising, computationally advantageous alternative for chromatographic data processing.
