摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
