A Novel Strategy to Screen and Profile Steviol Glycosides of Natural Sweeteners in Food Using ionKey/MS Ion Mobility Mass Spectrometry

27 Jul 2015

In this application note, we illustrate the selectivity of collision cross section (CCS) measurements used in combination with other recent MS technology enhancements for profiling complex mixtures. A combination of high resolution mass spectrometry and high efficiency ion mobility based measurements and separations is used. Ion mobility is a rapid orthogonal gas separation phase technique that allows another dimension of separation to be obtained within an LC timeframe. Compounds can be differentiated based on size, shape, and charge.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.
