Order if mass spectrometer
WebIn the most basic terms, mass spectrometry is a sensitive technique used to detect, identify and quantitate molecules based on the molecule’s mass-to-charge (m/z) ratio. How it works All mass spectrometers have three primary components; an ion source, a mass analyzer, and an ion detector. WebA mass spectrum is generated, which shows the different m/z values of ions present, and their relative abundance. Summary. Now you know has a mass spectrometer works – just remember the four stages in order – ionisation, acceleration, deflection, and detection. You should make sure to study a diagram of a mass spectrometer – a frequent ...
