Tandem Mass Spectrometry, often referred to as MS/MS, is a method that involves two consecutive stages of mass spectrometry. It is designed to provide enhanced specificity and sensitivity compared to single-stage mass spectrometry techniques. Tandem Mass Spectrometry involves a two-stage mass analysis process, offering superior analytical capabilities. In the first stage, also known as the precursor ion selection, a mixture of ions generated from the sample is subjected to mass analysis. These ions are separated based on their mass-to-charge ratio (m/z) using an analyzer, typically a quadrupole or time-of-flight (TOF) analyzer. The mass analyzer selects a specific precursor ion of interest. The selected precursor ion is then subjected to fragmentation. This fragmentation can be induced by various methods such as collision-induced dissociation (CID) in a collision cell or electron impact. The result is the generation of product ions. The product ions are then analyzed in a second mass analyzer to determine their m/z ratios. The output of the second mass analyzer provides a mass spectrum of the product ions, allowing the identification and quantification of the compounds present in the original sample. The combination of precursor ion selection and product ion analysis is what makes Tandem Mass Spectrometry a powerful technique in pharmaceutical analysis. The fundamental principles of MS/MS encompass ionization, precursor ion selection, fragmentation, and product ion analysis:
