The use of traditional targeted quantitative methodologies, particularly chromatographic methods, is oftentimes consuming and inappropriate for the high-throughput screening needed today in many areas such as authentication or regulatory verification of quality and purity of fat and oil matrices. Although a targeted analytical method can detect a given analyte with high sensitivity and specificity, unknown compounds, such as contaminants or intentional adulterants, cannot be detected in this manner. This session addresses the urgent demand for rapid, untargeted screening analytical tools, particularly those based on spectral methods in conjunction with chemometrics.
