Application Worx

NIR/NIT model development simplified

 

 

 

Application worx G2 (AWX) is a chemometrics software package designed for
chemometric calibration development in near-infrared (NIR/NIT) spectroscopy.

AWX enables the prediction of chemical properties from a sample’s NIR/NIT spectrum.

Developing robust calibration models from spectral data and well-characterized reference samples typically requires significant expertise in chemometrics. Unlike many comparable tools, Application worx G2 is clearly structured and guides users through each step with a strong focus on workflow. Well-organized wizard screens provide comprehensive support, allowing even non-specialists to build calibrations using Multiple Linear Regression (MLR) or Partial Least Squares Regression (PLSR).

During calibration development, users can choose automated optimization options to improve model performance, while experienced analysts can also apply their own expertise at every stage. Processed spectra can be visualized in parallel, enabling obvious outliers or abnormal spectra to be identified and excluded immediately. The selected spectra used for model calculation can be saved as a new batch, supporting ongoing refinement and future model improvements.

Application worx G2 also allows multiple PLSR models—using different combinations of spectral pretreatments—to be calculated in parallel. Users can easily compare model performance and select the most suitable option.

Finally, Application worx G2 compiles applications that bundle calibrations for multiple product properties. These applications can then be used to predict the relevant properties from spectral data collected by NIR spectrometers.
