Mass spectrometry (MS) has evolved from being a qualitative tool to a highly quantitative one. Recent advancements include the development of tandem mass spectrometry (MS/MS), which provides structural information about molecules by breaking them into smaller fragments. Additionally, the advent of high-resolution mass spectrometry (HRMS) allows for the precise measurement of molecular masses, which is crucial for identifying and quantifying complex biomolecules in proteomics and metabolomics.
