Abstract:
1. A system for performing analysis of at least one analyte present in a solid sample, comprising: a laser source for emitting a laser beam toward a specimen on a specimen stage to generate ablated analyte; a solvent dispensing and extraction system, the solvent dispensing and extraction system dispensing a solvent adjacent to a surface of the sample such that at least a portion of the ablated analyte can be dissolved in the solvent, wherein the solvent dispensing and extraction system forms a liquid microjunction between the solvent dispensing and extraction system and a surface of the specimen, the laser beam being focused at sample material within the microjunction, where the solvent dispensing and extraction system comprises a sampling probe for dispensing the solvent; and where the laser directs the laser beam through the sampling probe to the specimen; the solvent dispensing and extraction system having structure for extracting the analyte-containing solvent for analysis.
