Abstract Metabolomics approaches. such as direct analysis in real time-high resolution mass spectrometry (DART-HRMS). allow characterising many polar and non-polar compounds useful as authentication biomarkers of dairy chains. By using both a partial least squares discriminant analysis (PLS-DA) and a linear discriminant analysis (LDA). https://allfixelectricales.shop/product-category/wiring-harness-drain-hose/
