Laser-based ion mobility spectrometer for the direct analysis of aromatic compounds in liquids

Selective ionization of marker molecules in fuels by laser-based ion mobility spectrometry (LIMS)

“…photofragmentation, charge transfer reaction monitoring, trace detection and aromatics sensing. [31][32][33][34][35][36] In this study, we present qualitative and quantitative analysis of markers in fuels (petrol/diesel) using REMPI-IM spectrometry without chromatographic pre-separation. Fuel as a complex matrix with many PAHs required the use of laser wavelengths above 300 nm, or even 350 nm to obtain easily interpretable marker signals.…”
