Benefit

The NIR Calibration service offers the following benefit: Saving money
  • Improving the accuracy and reliability of already used NIR calibration models have high potential in various manufacturing processes as well as in quality assurance.
  • increased accuracy of analysis => better control of the production process => optimum process flow => better quality => less waste => more throughput.
  • quick and inexpensive to create professional NIR calibration models.
  • relief of their own staff
Time savings
  • for data cleaning (increasing data quality) – missing data, outlier search, wrong data (conflicting information), outlier removal
  • for the search for the optimal NIR model parameter settings (calibration set, wavelength selection, data pretreatments, factor selection)
  • for the calculation of different variations of the model
  • for the validation, evaluation and selection of the optimal model (error, SEP, RMSEP, RMSEC, RPD, fit, R2, bias, slope, …)
  • time-consuming calculation of huge calibration models
  • no long trial and error and waiting in the used NIR software until the calibrations seems to work
NIR analytical accuracy
  • higher reliability due to accuracy and robustness of NIR calibration models
  • the possibility of comparison with your own created or already existing or purchased NIR calibrations
  • what performance increase of analytical accuracy is possible
  • improvement of robustness with respect to change of the product matrix and possible instruments drift
Professional NIR calibration models
  • decades of experience in chemometrics for NIR spectroscopy
  • based on theoretical and applied good practice and know-how
  • application of various guidelines and rules
  • application of vendor-independent NIR chemometric software
  • outsourcing of NIR calibration method development and calibration equation maintenance
  • improving the robustness of NIR prediction model
  • avoid traps and pitfalls of the complicated chemometrics
Detailed results
  • The service provides optimal calibration settings for your NIR data.
  • You get full insight into the NIR calibration, as it is produced and detailed statistical values as a performance index assisted with graphics.
