This animation follows sample molecules from ionization through mass filtering, fragmenta The dietary supplements with claimed antioxidant activity constitute a substantial part of the dietary supplement market. In this study, we performed the LC-QTOF-MS analysis and investigated the activity profiles of popular antioxidant dietary supplements from different chemical groups in terms of quality control. least in principle, it provides the capability to identify the species corresponding to each chromatographic peak through its unique mass spectrum. Figure 1.1: The power of the LC-MS technique to separate and identify each component of a complex mixture 1.1 Scope of this guide FTICR-MS (Orbitrap technology uses similar principles) ions trapped in a cell inside a strong magnetic field and move in circular orbits in a plane perpendicular to magnetic field RF electrical potential is applied to transmitter plates causing trapped ions to be excited into larger circular orbits Identification of unknown chemical entities is a major challenge in metabolomics.

In LC-MS charge may also be applied to the molecule via association with other charged molecules –for example a proton (H+). Such ions are produced in LC/MS systems by the use of strong electric fields in the vapour or condensed phase.

Important Notes p.3 Crawford Scientific www.chromacademy.com 3 Definitions LC/MS is a hyphenated technique, which combines the separating power of High Performance Liquid Chromatography (HPLC), with the detection power of mass History of LC-MS. The coupling of chromatography with MS is a well developed chemical analysis strategy dating back from the 1950s. Gas chromatography (GC)–MS was originally introduced in 1952, when A. T. James and A. J. P. Martin were trying to develop tandem separation - mass analysis techniques.

The following general principles apply: - Users are expected to prepare samples in their own laboratory and transfer them to the instrument room ready for analysis. - Samples concentrations are not supposed to exceed 0.5 mg/mL for molecules below 1,000 Da, or 0.1 mg/mL for larger ones.

High-resolution mass spectrometry is a powerful tool in clinical analysis but remains less explored due to its lower dynamic range and sensitivity compared to triple quadrupoles.
