A plurality of refractive lens elements are provided that are fabricated from a common refractive material. The refractive lens elements are shaped and oriented to optically correct for monochromatic aberrations. A metalens is provided. The metalens optically corrects for the chromatic aberrations.

Abstract: Disclosed are systems and methods for automated chromatographic peak detection and refinement in high-throughput LC-MS/MS datasets, applicable to both proteomics and metabolomics. The invention integrates signal smoothing, apex detection, boundary assignment, and machine learning-based quality scoring into a fully automated pipeline. The system supports multiple acquisition modes (e.g., DIA-PASEF, Orbitrap), chromatographic strategies (C18, C30, HILIC), and biological matrices. Detected peaks are refined using second derivative and percentile-based baseline logic and scored by an XGBoost classifier trained on curated datasets. Quantification-ready outputs are suitable for biomarker panel development, quality control, and diagnostic assay construction. The invention substantially reduces manual curation time while improving reproducibility across samples and platforms.
