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: A dual spray chamber apparatus is described. In one or more implementations, the dual spray chamber apparatus includes a first cyclonic spray chamber for receiving an aerosol and conditioning the aerosol to separate a first conditioned portion of the aerosol from a second portion of the aerosol. The first cyclonic spray chamber defines a first chamber interior and comprises an input port in fluid communication with the first chamber interior. The dual spray chamber apparatus also includes a second spray chamber coupled with the first cyclonic spray chamber for receiving the first conditioned portion of the aerosol and further conditioning the first conditioned portion of the aerosol. The second spray chamber defines a second chamber interior and comprises an output port for expelling a first further conditioned portion of the first conditioned portion of the aerosol from the second chamber interior.

Abstract: Systems and methods are described for calibrating an analytical instrument analyzing a plurality of sample matrices in series. A system embodiment can include, but is not limited to, a sample analysis device configured to receive a plurality of samples from a plurality of remote sampling systems and to determine an intensity of one or more species of interest contained in each of the plurality of samples; and a controller configured to generate a primary calibration curve based on analysis of a first standard solution having a first sample matrix by the sample analysis device and generate at least one secondary calibration curve based on analysis of a second standard solution having a second sample matrix by the sample analysis device, the controller configured to associate the at least one secondary calibration curve with the primary calibration curve according to a matrix correction factor.

Abstract: Systems and methods are described to determine whether a sample transmitted through a transfer line from a remote sampling system contains a suitable sample to analyze by an analysis system. A system embodiment includes, but is not limited to, a sample receiving line configured to receive a liquid segment a first detector configured to detect the liquid segment at a first location in the sample receiving line; a second detector configured to detect the liquid segment at a second location in the sample receiving line downstream from the first location; and a controller configured to register a continuous liquid segment in the sample receiving line when the first detector and the second detector match detection states prior to the controller registering a change of state of the first detector.

Abstract: A system includes an analysis system at a first location and one or more remote sampling systems at a second location remote from the first location. A sampling system can be configured to receive a remote liquid sample. The system also includes a sample transfer line configured to transport gas from the second location to the first location. The sample transfer line is configured to selectively couple with a remote sampling system for supplying a continuous liquid sample segment to the sample transfer line. The system can further include a sample receiving line at the first location. The sample receiving line is configured to selectively couple with the sample transfer line and the analysis system to receive the continuous liquid sample segment and supply the sample to an analysis device.
