Tandem Mass Spectrometry (MS/MS)

Tandem Mass Spectrometry (MS/MS) is an advanced analytical technique used to identify and quantify molecules, especially complex compounds like proteins or metabolites. It works by first measuring the mass of molecules in a sample (MS1), then selecting specific ions and breaking them into smaller pieces. The resulting fragments are analyzed again (MS2), providing detailed structural information. This dual-stage process allows for precise identification and detailed analysis of complex mixtures, making MS/MS essential in fields like medical diagnostics, pharmaceuticals, and research for understanding molecular composition and structure.
