Analysis of Methylxanthines by PDA Detector and Mass Detector
Note Number: AS/MSD-004
Chromaster 5610 MS detector is a new mass detector, designed for LC users, and it is different from conventional mass spectrometers. This time, the analysis examples of methylxanthines such as caffeine are introduced here. These components are often contained in coffee, cacao products, and supplement drinks. Methylxanthines have a common basic molecular structure. Therefore, UV spectral patterns are very similar and the differentiation based only on the UV spectra is difficult. However, a mass detector can provide the mass information unique to a component, and thus the identification accuracy is improved.
