Overview
Mass spectrometry (MS) is a powerful analytical technique used to measure the mass-to-charge ratio of ions, providing valuable insights into the elemental or isotopic signature of a sample, the masses of particles and molecules, and the chemical identity or structure of molecules and other chemical compounds. With applications in fields such as chemistry, biology, pharmacology, and environmental science, mass spectrometry has become an indispensable tool for researchers and scientists. According to the National Institutes of Health, mass spectrometry has revolutionized the field of proteomics, enabling the identification and quantification of thousands of proteins in a single experiment. The American Chemical Society has also recognized the significance of mass spectrometry, awarding numerous prizes for innovations in the field.
Origins & History
Mass spectrometry is used in a wide range of applications, from drug discovery to environmental monitoring, and has been recognized as a key technology in the Human Proteome Project.
How It Works
The mass spectrometry process involves several key steps, including ionization, separation, and detection. Ionization is typically achieved using techniques such as electrospray ionization or matrix-assisted laser desorption ionization. The resulting ions are then separated according to their mass-to-charge ratio using a variety of techniques, including quadrupole mass spectrometry and time-of-flight mass spectrometry. The separated ions are then detected using a detector, such as a Faraday cup or a microchannel plate. The Thermo Fisher Scientific company has developed a range of mass spectrometry instruments, including the Orbitrap and the TSQ.
