Posters from CAC 2026

The XX Chemometrics in Analytical Chemistry International Conference (CAC) was held in Tarragona, Catalonia (Spain) June 29 to July 3. The conference began with short courses, (including our Non-linear Machine Learning for Calibration and Classification), and there were many great oral presentations. But my favorite was the poster session which ran for the duration of the conference.

The poster session at CAC attracted many participants, well over 100 posters were presented. I always look for posters (and talks) that utilize our software. It’s always fun and often enlightening to see what researchers are doing with our software, what methods they are using and what types of data they are working with. I list below the 15 posters I found which utilized PLS_Toolbox, MIA_Toolbox or Solo. Click on the links for copies of the posters.

• V.G.K. Cardoso et. al., Hyperspectral Imaging and Chemometrics for Monitoring Formulation, Processing and Homogeneity in Hybrid Sausages
• N. Cavallini et. al., Measure Your Bratwurst: Chemometric Strategies for Detecting Mechanically Separated Meat with NIR Spectroscopy
• M.J.M. Firmino et. al., Comparison of multivariate calibration models for methanol quantification in distilled beverages
• A.N. Ito et. al., Detection of Starch Adulteration in Parmesan Cheese using Portable NIR Spectroscopy and Chemometric Analysis
• C. Malegori et. al., A Multivariate investigation of the factors governing rare earth element accumulation patterns in soil–plant systems
• E. Messias et. al., Volatile Composition of Coffea Canephora Subjected to Malting using SHS-GC-MS and ANOVA-Simultaneous Component Analysis (ASCA)
• D. Mostoles et. al., Non-Targeted LC-HRMS for the Authentication of Honey from Diverse Geographical Origins
• V. Navarro-Esteve et. al., An ATR-FTIR Methodology for Determining the Urinary Albumin-to-Creatinine Ratio and Screening for CKD  
• S. Pellacani et. al., A Fused Approach using Ion Mobility Spectrometry and Spectroscopy for Honey Authentication
• S. Poulsen et. al., Near-Infrared Shortcuts? Exploring NIR for Faster Tablet Stability Evaluation 
• A. Safarnejad et. al., ROI-MCR-Based Pipeline for Resolving Complex LC-QTOF-MS Lipidomic Data in Rice Exposed to Napropamide
• Ángel Sánchez-Illana et. al., Multimodal Strategies for Chronic Kidney Disease Screening from Direct Urine Analysis: ATR-FTIR and Voltammetry with Screen-printed Electrodes
• E. Sikorska et. al., Fluorescence Fingerprinting of Raspberry and Strawberry Juices for Authenticity Assessment using  A-TEEM Spectroscopy
• B.M. Wise et. al., Volume Fractions and Apparent Volume Fractions
• B.M. Wise and R. Bro, Overfit < 1? Understanding Why Cross-validation Error can be Less than Fit Error

That’s quite a range of data types and methods and some really excellent work! And yes, those last two posters are mine. I always enjoy presenting posters because it gives you a chance to talk to people one-on-one and have more interaction. And it’s an especially great format for new researchers to present and discuss their work.

Thanks and congratulations to the organizers of CAC including Chairs Ricard Bouqué and Anna de Juan and the rest of the local committee for putting on a great conference!
