Q

Electrospray Ionization

A

Electrospray makes charged ions and sprays them in fine mist to be evaporated and drawn into mass analyzer. Electric field of opposite polarity of charged ions draws them into mass analyzer.

Q

Process of Mass Spectrometry & Parts of Mass Spectrometer Correlated to Process

A
  1. The sample has separate compounds due to Chromatography.
  2. Ions are made in gas phase. (Electrospray Ionization)
  3. Ions are sorted and separated based on mass/charge ratio. (Mass Analyzer)
  4. (Electron Multiplier) counts ions and converts them to electrons. The current is processed by electric circuit and used as Data System.
  5. Mass Spectrum & Data Output is made.
