mass spectrometer

A mass spectrometer is an analytical device used to identify and measure the components of a sample by separating its molecules based on their mass and charge. The process involves ionizing the sample to create charged particles, which are then propelled through electric and magnetic fields. These fields deflect the ions differently depending on their mass-to-charge ratio. A detector records the ions' arrival times or positions, producing a spectrum that reveals the composition and relative abundance of the sample's molecules. This technique is widely used in chemistry, biology, and environmental science for precise molecular analysis.
