Calibration of spectroscopic analyzers using standardized spectral responses
A recently granted patent (Publication Number: US11921035B2) discloses a method for enhancing the calibration process of a spectroscopic analyzer by using standardized analyzer spectral responses. The method involves analyzing multi-component samples in a first state to create spectral models, comparing the spectra of first-state and second-state portfolio samples, determining variances at different wavelengths, and transforming material spectra based on the standardized analyzer spectra portfolio to output corrected material spectra. The method also includes outputting signals indicative of material properties, updating spectral models with corrected material spectra, and transferring spectral models to the same analyzer after changes to define it in a second state.
Furthermore, the patent describes a spectroscopic analyzer assembly that implements the method for calibration enhancement. The assembly includes a spectroscopic analyzer with an analyzer controller that outputs sample spectra, determines spectral models, compares and analyzes portfolio samples, and transforms material spectra based on standardized analyzer responses. The analyzer controller can output signals indicating material properties, create material databases, determine variances, and alter gains associated with analyzer sources or detectors. The assembly is designed to facilitate calibration and recalibration of the analyzer after changes, ensuring accurate and consistent analysis of materials in different states. The disclosed method and assembly aim to improve the accuracy and reliability of spectroscopic analysis processes by utilizing standardized analyzer spectral responses for calibration purposes.
