Classification and Phenolics Analysis of Red Wines with A-TEEM Molecular Fingerprinting
HORIBA Scientific has developed Aqualog®, an analytical instrument based on the simultaneous measurement of Absorbance, Transmittance, Fluorescence Excitation and Emission Matrix (A-TEEM™). Aqualog reports NIST-traceable A-TEEM fingerprints which can be evaluated using multivariate statistics such as PARAFAC (Parallel Factor Analysis), PCA (Principal Components Analysis), CLS (Classical least Squares) and PLS (Partial least Squares Analysis). Importantly A-TEEM fingerprints yield qualitative and quantitative composition of key flavor and color determinants in wine and spirits that are not discernible with simple Absorbance or Transmission data analysis.
