If tandem mass spectrometry is combined with a chromatographic separation,what is added to the physical property characterization of the compound being analyzed?

Question

Quizplus · Accepted Answer

Chromatographic separation, typically using liquid chromatography (LC), separates the compound being analyzed into its individual components based on their physical and chemical properties such as molecular weight, polarity, and affinity with the stationary phase. The retention time, which is the time it takes for each component to travel through the chromatographic column and reach the detector, is a measure of its physical property. When tandem mass spectrometry is combined with chromatographic separation, the retention time adds an additional physical property characterization dimension as it provides information on the behavior of the compound in the chromatographic system.
