Matrix-assisted laser desorption ionisation (MALDI) uses a laser to absorb energy from a matrix to create ions with minimal fragmentation from large molecules. It can analyse biopolymers such as DNA, proteins, peptides, carbohydrates, and other organic macromolecules. In MALDI time-of-flight (TOF) mass spectrometry (MS), a TOF analyser measures the mass-to-charge (m/z) ratio of the charged molecules.
