Recently, matrix-assisted laser desorption/ionization (MALDI) matrices, which consist of aromatic acids with benzene rings, have been developed using this technique.
Web16 feb. 2024 · What is Mass Spectrometry? Mass spectrometry is a type of chemical analysis that measures the mass of ions, and calculates the relative abundance of each of those ions within the sample. It’s a kind of instrumental analysis, which means the sample is processed and measured within a device, or instrument, called a mass spectrometer.
