A laser-ablation-based analytical system can include a sample chamber input, a make-up gas input, a vacuum pump, and an output flow. The sample chamber input can be configured to deliver a sample chamber gas flow comprised of combination of a laser-ablated sample and a sample-carrier gas from a sample chamber. The make-up gas input can be configured to provide an amount of make-up gas to supplement the combination of the laser-ablated sample and the sample-carrier gas. The vacuum pump can be fluidly connected to the sample chamber input and the make-up gas input, the vacuum pump configured to create a negative pressure in a sample transport gas downstream of the vacuum pump, the sample transport gas including the make-up gas, the laser-ablated sample, and the sample-carrier gas. The output flow can be configured to deliver the sample transport gas from the vacuum pump to a detection device.

Controlled separation of laser ablation sample gas for direction to multiple analytic detectors

A laser ablation system includes a sample chamberconfigured to accommodate a targetwithin an interiorthereof, a sample generatorconfigured to remove a portion of the target(which may be subsequently captured as a sample) and an analysis systemconfigured 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 chamberincludes an injection nozzleconfigured to introduce, into the interior, a fluid such as a carrier gas.
