Application Note: Profiling Flavonoid Isomers in Highly Complex Citrus Juice Samples Using UPLC Ion Mobility Time-of-Flight Mass Spectrometry
3 Nov 2012

The presence of flavonoids in citrus juices has attracted widespread attention because of their biological and physiological benefits. Considering these associated health benefits, the impact of food processing and preparation on flavonoid content demands a greater understanding. In this application note a Waters ACQUITY UPLC system combined with a SYNAPT G2-S Mass Spectrometer was used to specifically and unambiguously identify the components present in citrus juices. High Definition Mass Spectrometry enabled compounds can be differentiated based on size, shape, and charge, as well as mass.
