Study Notes
Mass Spectrometry
- Mass spectrometry is an analytical technique that involves ionization and fragmentation of molecules for mass and structural analysis.
- It consists of five basic parts: high vacuum system, sample handling system, ion source, analyzer, and detector.
Principles of Mass Spectrometry
- The principle of mass spectrometry involves sorting of gaseous ions in electric and magnetic fields according to their mass-to-charge ratios.
- Instruments used in mass spectrometry studies are called mass spectrometers and mass spectrographs.
Steps in Mass Spectrometry
- Ionization: conversion of sample into charged particles.
- Acceleration: speeding up ions to give them the same kinetic energy.
- Deflection: deflecting ions with a magnetic field, with lighter ions deflecting more.
- Detection: detecting deflected ions and determining their mass-to-charge ratio.
