Application worx G2
NIR model development simplified
Application worx is a chemometric software package
that is designed for calibration development in the field of NIR spectroscopy.
AWX is used to predict chemical characteristics of the near-infrared (NIR) spectrum of a sample.
Usually vast knowledge and expertise is required to calculate a calibration model based on spectral data of well-known reference samples using chemometrics.
This is where Application worx differs from similar software because it is well structured, guides the user through all steps and emphasises the work flow.
Well-arranged wizard windows give comprehensive assistance and thus even allow the layman to develop a calibration utilising multiple linear regression (MLR)
or partial least squares regression (PLSR).
Throughout the calibration development process with Application worx it is possible to choose the automated option to improve the calibration model successively respectively iteratively and the expert is still able to incorporate invaluable experience into the calibration development.
Application worx compiles an application with calibrations for various properties for the product the user wishes to analyse and the properties can be analysed quickly and instantaneously using an NIR spectrometer.
