electrospray laser desorption ionization mass spectrometry

acronym: ELDIMS
mentioned: laser ablation electrospray ionization (LAESI), matrix-assisted laser desorption electrospray ionization (MALDESI)
https://doi.org/10.1351/goldbook.09184
Measurement method in which a mass spectrometer is used to measure the ratio of mass to charge quotient and the abundance of ionized entities emitted from a sample in air via ablation by a focused pulsed laser while simultaneously directing an electrospray jet through the desorbed plume to enhance sample ionization.
Notes:
  1. The desorption mechanism is thermal.
  2. Both positive and negative ions are observed.
  3. With the addition of a matrix on the sample, this is termed matrix-assisted laser desorption electrospray ionization (MALDESI).
  4. With the use of an infrared laser for ablation, this has sometimes been termed laser ablation electrospray ionization (LAESI).
