The Detection of Polyphenolics in Food and Drink by LC/MS/MS
13 Jun 2012Catechins are polyphenolic antioxidant plant metabolites found in a variety of foods including fruits, wine, beer, chocolate, and most abundantly in tea. This study shows the use of LC-MS for the determination of 8 known catechins in samples such as tea and wine. The method demonstrates the efficient separation and detection and of these compounds by LC-MS and uses advances in HPLC column phases and high pressure separations to improve sensitivity and speed up the analysis.

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.
