PEAXACT is a software for the analysis of spectra and chromatogrammes.

Beyond the established data-driven methods like PLS, PEAXACT exclusively provides the Indirect Hard Modeling method. IHM uses the physical structure behind mixture spectra, so that less calibration samples are required.

Fundamentals for PEAXACT were set at AVT.PT. In cooperative projects with the research transfer organisation AixCAPE and industrial users, PEAXACT was evaluated and further developed. Since 2011 PEAXACT is commercially available at S-PACT GmbH, a spin-off company of AVT.PT.
