Abstract
A laser ablation system includes a sample chamber 102 configured to accommodate a target 104 within an interior 106 thereof, a sample generator 108 configured to remove a portion of the target 104 (which may be subsequently captured as a sample) and an analysis system 110 configured to analyze a composition of the sample. A sample capture cell in the chamber proximate to the target has a capture cavity configured to receive target material, a first inlet configured to transmit a flow of a carrier gas from a first location adjacent to an exterior of the capture cell into a region of the capture cavity; and an outlet configured to receive carrier gas from another region of the capture cavity. The sample chamber 102 includes an injection nozzle 120 configured to introduce, into the interior 106, a fluid such as a carrier gas.
