Basic Principles of Mass Spectrometry
Mass spectrometry involves ionizing samples, separating ions by mass-to-charge ratio, and detecting them. Understanding ionization, mass analyzers, and detectors is fundamental.
Today is 12/13/2025 03:34:16 ().
Ionization Techniques (EI, CI, ESI, MALDI)
Ionization is the crucial first step in mass spectrometry, converting neutral molecules into ions for analysis. Several techniques exist, each suited for different sample types. Electron Ionization (EI), a “hard” ionization method, fragments molecules extensively, providing structural information but potentially losing molecular weight data.
Chemical Ionization (CI) offers a “softer” approach, reducing fragmentation. Electrospray Ionization (ESI) is ideal for large biomolecules like proteins, producing multiply charged ions. Matrix-Assisted Laser Desorption/Ionization (MALDI) is another soft technique, commonly used for polymers and biomolecules, embedding the sample in a matrix that absorbs laser energy.
