Symbion QT 2.5. chemometrics software provides Parametric Data Cleaning, a technique that automates the handling of data compromised by excessive noise or other artifacts. Key cleaning parameters are under the control of the analyst, allowing chemometric optimization under a wide range of analytical situations. Parametric Data Cleaning provides important benefits when developing analyzer applications using near-infrared, UV-Visible, mid-infrared and Raman spectroscopy. It is especially appropriate for high-resolution, gas-phase analysis. QT Model Builder’s workflow approach guides beginner and expert alike through the process of assembling the data needed to build, validate and correctly deploy multivariate analytical solutions, and the resulting calibrations are fully documented. The workflow approach is based on the way expert chemometricians handle these tasks.
