Mass spectrometry is particularly relevant when studying proteins. With this instrument, the determination of protein structure, function, and interactions is possible. A mass spectrometer can also detect post translational modifications on complex mixtures, perform both quantitative and qualitative analysis, and monitor enzyme react
