US 2014/0227776 A1 · LASER ABLATION CELL AND TORCH SYSTEM FOR A COMPOSITIONAL ANALYSIS SYSTEM

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.

Dependent claims

An apparatus for handling target material removed from a laser ablation site of a target, the apparatus comprising:

a sample capture cell configured to be arranged operably proximate to the target, the sample capture cell including:
a capture cavity having an opening formed in a surface of the capture cell, wherein the capture cavity is configured to receive, through the opening, target material ejected or generated from the laser ablation site when the sample capture cell is operably proximate to the target;
a first inlet in fluid communication with the capture cavity, wherein the first inlet is 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 in fluid communication with the capture cavity and configured to receive carrier gas from another region of the capture cavity.
