Abstract: A system for determining an analyte by inductively coupled plasma mass spectrometry (ICPMS) includes a sample introduction device having a heated cyclonic spray chamber. The system is configured to introduce sample that includes a metal and/or a metalloid having an organic interferent. The system also includes an inductively coupled plasma mass spectrometry device with a collision/reaction cell configured to receive a mixture of gases including both ammonia and hydrogen. A method includes introducing a sample to plasma to produce a characteristic spectrum associated with an elemental composition of the sample. The method also includes introducing both ammonia and hydrogen to a collision/reaction cell to remove carbon-based interferences to detection of the sample prior to determining the elemental composition of the sample.

Abstract: Valve assemblies are described that provide flow paths in substantially indirect opposition for fluids injected into the valve assemblies for mixing. A valve assembly includes a first valve member having ports configured to receive a first fluid and a second fluid. The valve assembly also includes a second valve member coupled adjacent to the first valve member. The valve assembly defines a first flow path for the first fluid and a second flow path for the second fluid. The first flow path extends from one of the ports of the first valve member toward an interface between the first valve member and the second valve member, and the second flow path extends from a channel defined by the second valve member toward the interface between the first valve member and the second valve member. The second flow path is in substantially indirect opposition to the first flow path.

Abstract: Systems and methods are described for analyzing local minimum data from spectrometry data for the determination of nanoparticle detection thresholds are described. In aspects, a histogram of the spectrometry data is used to search for potential local minimum values, which are subsequently validated to establish a nanoparticle detection threshold for the spectrometry data, with ion intensity values less than the nanoparticle detection threshold being attributable to signal background.
