Laser Assisted
Electrospray-assisted laser desorption/ionization (ELDI) relies on a laser to the desorption of material into the electrospray plume. With matrix-assisted laser desorption electrospray ionization (MALDESI), a nitrogen laser is used to desorb material into the electrospray. MALDESI has been used with MALDI matrix materials. Laser ablation electrospray ionization (LAESI) uses an infrared laser for ablation of the sample material. The term laserspray ionization has been used to describe transmission mode laser ablation of matrix/analyte mixtures to produce highly charged electrospray-like molecular ions.

Famous quotes containing the word assisted:
“To anticipate, not the sunrise and the dawn merely, but, if possible, Nature herself! How many mornings, summer and winter, before yet any neighbor was stirring about his business, have I been about mine! No doubt, many of my townsmen have met me returning from this enterprise, farmers starting for Boston in the twilight, or woodchoppers going to their work. It is true, I never assisted the sun materially in his rising, but, doubt not, it was of the last importance only to be present at it.”
—Henry David Thoreau (1817–1862)
