- Scope
- There is a correlation between changes in sample component content and corresponding changes in near-infrared spectra. Use the diffuse reflection method to obtain the near-infrared diffuse reflectance spectrum of the calibration sample set, select an appropriate chemometrics correction method, correlate the near-infrared spectrum of the calibration sample set with its corresponding main chemical component content, establish a calibration model, and use the verification sample set to perform the calibration Verify the effectiveness of the model. Use the verified calibration model and the near-infrared diffuse reflectance spectrum of the sample to calculate the content of the main chemical components of the sample to be tested.
