These include Atmospheric Pressure Chemical Ionization, Atmospheric Pressure Photoionization (APPI), Electrospray ionization (ESI) and Laser Desorption Ionization.
Atmospheric pressure chemical ionization (APCI), a widely used ionization technique in mass spectrometry, is similar to atmospheric pressure photoioni…
All mass spectrometers require the molecules to be in the gas phase and charged (ionized either positive or negative). In this technique, UV light pho…
Electrospray ionization (ESI) is a popular technique in mass spectroscopy for ionizing samples before they are measured. ESI works well with heavier c…
MALDI, a method of ionization that has been widely used since its introduction in the late 1980s, has been of great help to scientists studying polyme…
