For precise, robust and transferable spectral calibrations
The development of spectroscopic calibrations
Industrials, technical centers, equipment manufacturers, you use near infrared (NIR), mid infrared (FTIR, MIR), Raman, Ultraviolet (UV), LIBS, Fluorescence, etc. to control the quality of your products and processes. These optical measurements being so-called secondary data, it is necessary to correlate them with reference analyzes by developing prediction models, called spectroscopic calibrations.
Composed of multidisciplinary experts in data analysis and spectroscopy, Ondalys team assists you in the development of these spectral calibrations and the optimization of their robustness.
You wish to :
precise and robust models for your spectrometers
your existing spectroscopic calibration
these calibrations from one spectrometer to another
Thanks to our knowledge in Chemometrics and Machine Learning as well as vibrational spectroscopy and its implementation in laboratory or embedded on pilots or industrial process lines, we assist you in the different stages of development and maintenance of spectroscopic calibration models:
- Spectroscopic preprocessing and selection of variables
- Multivariate calibration (PLS, SVMR, ANN, local regression,…)
- Classification (PLS-DA, SIMCA, SVM, Classification trees – RF, XGBoost,…)
- Validation and Robustness of models
- Transfer of calibrations (standardization, orthogonalisation,…)
- Model update
We develop your calibrations with all the Chemometrics software on the market (Unscrambler®, SOLO® or PLS_Toolbox® in the MATLAB® environment, SIMCA®, etc.), as well as those provided by spectroscopy equipment manufacturers (OPUS, WinISI, NIRCal, TQ Analyst, etc…), but also free software (R, Python…).
Our expertise for the analysis of your spectral data
With more than 15 years of experience in data analysis (Chemometrics and Machine Learning), in particular applied to measurements from spectrometers, the experts of our teams support you at each stage of your projects.

How pleasant it is to be able to face complexity in good humor and with the sense of measure! It is this pleasure that I personally always had in contact with Ondalys team during our collaborations.
