The Unscrambler X is a commercial software product for multivariate data analysis, used for calibration of multivariate data which is often in the application of analytical data such as near infrared spectroscopy and Raman spectroscopy, and development of predictive models for use in real-time spectroscopic analysis of materials. The software was originally developed in 1986 by Harald MartensHarald Martens, Terje Karstang, Tormod Næs (1987) Improved selectivity in spectroscopy by multivariate calibration Journal of Chemometrics 1(4):201-219 and later by CAMO Software. After the acquisition of CAMO by Aspen Technology in 2020, Unscrambler is now owned by Aspen.
Functionality
The Unscrambler X was an early adaptation of the use of partial least squares (PLS).Abdi, H. (2003) Partial least squares regression In Lewis-Beck, M., Bryman, A., Futing, T. (Eds.).

The software is used in spectroscopy (IR, NIR, Raman, etc.), chromatography, and process applications in research and non-destructive quality control systems in pharmaceutical manufacturing,M.R.
