Abstract: A method includes supplying a reagent to a column, where the column is configured to purify an element from a sample matrix for isotopic analysis. The method also includes loading the column with the sample matrix, and supplying a second reagent to collect the element retained by the column. The method further includes loading the column with a second sample mixture, and collecting an element from the second sample mixture retained by the column. A column configured to separate an element from a sample matrix for isotopic analysis includes a resin configured to retain the element. The column also includes a first frit disposed of a first end of the column and a second frit disposed of a second end of the column. The column is configured to receive a first reagent in a first flow direction and a second reagent in a second flow direction different from the first flow direction.

Abstract: Systems and methods are described to provide speciation of silicon species present in a remote sample for analysis. A method embodiment includes, but is not limited to, receiving a fluid sample containing inorganic silicon in the presence of bound silicon from a remote sampling system via a fluid transfer line; transferring the fluid sample to an inline chromatographic separation system; separating the inorganic silicon from the bound silicon via the inline chromatographic separation system; transferring the separated inorganic silicon and bound silicon to a silicon detector in fluid communication with the inline chromatographic separation system; and determining an amount of one or more of the inorganic silicon or the bound silicon in the fluid sample via the silicon 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.

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: A sample identification system for an automated sampling and dispensing device is described. In an example implementation, the sample identification system includes a sample probe configured to contact a sample positioned within a sample vessel. Further, the sample identification system includes an identifier capture device configured to measure a sample identifier associated with the sample vessel and generate a data signal in response thereto, where the data signal corresponds to an identity of the at least one sample. During operation, the identifier capture device scans a sample holder, a sample vessel, or a table top of the automated sampling and dispensing device to measure the sample identifier and to generate the data signal in response thereto.

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.
