Abstract: Systems and methods are described to concentrate and homogenize a remote sample for analysis. A sample concentration and homogenization system embodiment includes, but is not limited to, at least a first valve, at least a first column fluidically coupled to the first valve, a flow meter fluidically coupled with the first column when the first valve is in a first flow path configuration to measure an amount of the liquid sample passed through the first column, and a homogenization valve including a sample homogenizing loop in which the concentrated sample is homogenized.

Abstract: An analysis system includes a degassing cell, at least one first valve, and at least one second valve. The at least one first valve is fluidly coupled with a top of the degassing cell, the at least one first valve configured selectably connect the degassing cell to a displacement gas flow and to a vacuum source. The at least one second valve is fluidly connected with a lateral side of the degassing cell and separately fluidly connected with a bottom of the degassing cell. The at least one second valve is selectably coupled with any of a source of a sample-carrying fluid, a transfer line configured to deliver a sample to an analysis device, or a waste output.

Abstract: The present disclosure is directed to a system and a method for hydride generation. In some embodiments, the system includes an assembly for introducing hydride generation reagents into a mixing path or mixing container, where the assembly includes first chamber configured to contain a first hydride generation reagent and a second chamber configured to contain a second hydride generation reagent. A first plunger is configured to translate within the first chamber and cause a displacement of the first hydride generation reagent, and a second plunger is configured to translate within the second chamber and cause a displacement of the second hydride generation reagent. The assembly further includes base coupling the first plunger and the second plunger together.

Abstract: A system can include a valve assembly including a first valve and a second valve in fluid communication with the first valve. The valve assembly can be configured to deliver one or more of a sample, a chemical (e.g., an acid, a base, an organic chemical, etc.), and a standard via flow of a working fluid facilitated by one or more syringe pumps. Further, the one or more of the sample, the chemical, and the standard can maintain a physical separation from the one or more syringe pumps during delivery of the one or more of the sample, the chemical, and the standard.

Abstract: Systems and methods are described for systems and methods for integrated decomposition and scanning of a semiconducting wafer for organic and inorganic impurities. In an aspect, a method includes, but is not limited to, positioning a nozzle above a surface of a semiconducting wafer, the semiconducting wafer supported adjacent to or within an interior of a chamber body; introducing a first scan fluid including one or more organic fluids to an inlet port of the nozzle; directing a portion of the first scan fluid onto the surface of the semiconducting wafer to permit interaction between the scan fluid and one or more organic contaminants present on the surface of the semiconducting wafer; and removing the first scan fluid containing at least a portion of the one or more organic contaminants from the surface of the semiconducting wafer via the nozzle.
