Abstract:
1. A system for desorption and sampling of analyte present on a target surface the system comprising: a sonication probe including a capillary having a probe inlet end and a probe outflow end, the probe inlet end comprising a sampling tip and the probe outflow end being in fluid communication with the probe inlet end, the probe being coupled to a transducer so as to apply vibrational energy to the target surface at the probe inlet end for desorbing analyte from the surface; an irrigation assembly having an irrigation outlet end positioned proximate to or coaxially with the sonication probe sampling tip for providing a flow of irrigation fluid proximate to the probe inlet end, and at least one aspirator located and connected to aspirate a sample of desorbed analyte and irrigation fluid into the capillary probe inlet end from the target surface for passage through the capillary to an analysis instrument.
