laser ablation electrospray ionization mass spectrometry

acronym: LAESI
https://doi.org/10.1351/goldbook.09187
Measurement method in which a mass spectrometer is used to measure the ratio of mass to charge and the abundance of ionized entities emitted from a sample in air as a result of laser ablation and electrospray ionization.
Notes:
  1. The laser wavelength is usually in the infrared region.
  2. Both positive and negative ions are observed with the mechanisms involving protonation through water molecules and ionization through the Penning process.
