Desorption Atmospheric Pressure Photoionization
In desorption atmospheric
pressure photoionization (DAPPI), a heated nebulizer microchip is used to mix
UV-absorbing solvent (typically toluene) with nitrogen gas and produce a hot vapor
jet that is directed toward the sample deposited on a surface attached to a linear
