desorption atmospheric pressure photoionization mass spectrometry

initialism: DAPPI
https://doi.org/10.1351/goldbook.09180
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 desorption by a jet of hot solvent vapour and ionization by ultraviolet light.
Notes:
  1. The desorption mechanism is thermal.
  2. Both positive and negative ions are observed.
