Abstract: Systems and methods for automatic preparation of samples through evaporative sampling for subsequent analysis are described. A system embodiment includes, but is not limited to, a sample source configured to supply a sample; an evaporation container fluidically coupled with the sample source to receive the sample; a temperature control element operably coupled with the evaporation container to vaporize a liquid portion of the sample within the evaporation container, the evaporation container fluidically coupled with a gas input to receive a gas to transport vapor from the evaporation container; and a cooling system configured to receive the vapor from the evaporation container and to condense the vapor for collection.

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: A sample introduction system providing variable online dilution of a sample is described. In one or more implementations, a device includes a spectrometry analysis system that employs example techniques in accordance with the present disclosure includes an inline dilution environment, including a first valve assembly configured to prepare a sample by accepting at least one of the sample, a diluent, a carrier, or an internal standard, where the first valve assembly includes a first sample loop; and a second valve assembly configured to prepare the sample by accepting the sample from the first valve assembly, where the second valve assembly is coupled to the first valve assembly, and where the second valve assembly includes a second sample loop.

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 collecting and combining multiple scan samples from a surface of a semiconducting wafer. A system embodiment includes, but is not limited to, a scan nozzle configured to introduce a first scan solution to a surface of a semiconducting wafer to remove impurities from the surface to provide a first scan sample and retrieve the first scan sample, the scan nozzle further configured to introduce a second scan solution to the surface of the semiconducting wafer to remove residual impurities from the surface to provide a second scan sample and retrieve the second scan sample; and a collection vessel in fluid communication with the scan nozzle, the collection vessel configured to receive each of the first scan sample and the second scan sample from the nozzle and to mix the first scan sample with the second scan sample to provide a combined scan sample.

Abstract: Systems and methods for analyzing ultra-low level concentration nanoparticles in semiconductor cleaning chemicals by single particle inductively coupled plasma mass spectrometry (spICP-MS) are described. In aspects, the methods described herein include determination factors that are specific to each of the chemical matrix and the type of analyte associated with the nanoparticles present in a fluid sample for both a particle baseline intensity value and a nanoparticle detection threshold.

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.
