    Abstract: A sample identification system for an automated sampling device is described. A system embodiment includes, but is not limited to, a sample holder having a plurality of apertures configured to receive a plurality of sample vessels therein, the sample holder having one or more corresponding sample holder identifiers positioned proximate to the sample holder; and an identifier capture device configured to detect the one or more sample holder identifiers positioned proximate to the sample holder and generate a data signal in response thereto, the data signal corresponding to at least an orientation of the sample holder relative to a surface on which the sample holder is positioned.

    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: Systems and methods are described for isolating a sample at a valve prior to introduction to an analysis system, such as sample analysis via ICP-MS. A system embodiment can include, but is not limited to, a valve system including a first valve in fluid communication with a sample reservoir and a second valve configured to permit and block access of a vacuum source to the first valve; a sensor system configured to detect presence or absence of a fluid at the first valve; and a controller configured to control operation of the second valve to block access of the vacuum source to the first valve upon detection of the fluid at the first valve to isolate the fluid within the sample reservoir.

    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 for automatic sampling, digestion, and joining a plurality of sample introduction systems of a sample for subsequent analysis by ICP-MS are described. A system embodiment may include: a digestion vessel configured to receive a sample from a pressurized sample source; a shutoff valve configured to control a flow of the sample to the digestion vessel; a first syringe pump configured to introduce a reagent to the sample in the digestion vessel; a thermally-controlled block surrounding the digestion vessel and configured to control the temperature of the digestion vessel, wherein the thermally-controlled block increases the temperature of the digestion vessel to a first set temperature before digestion and wherein the thermally-controlled block decreases the temperature of the digestion vessel to a second set temperature after digestion; a level sensor configured to measure a level of the sample within the digestion vessel; a second syringe pump configured to introduce deionized water to the digestion vessel after digestion, based at least in part on the level measured by the level sensor; and a connector valve configured to receive digested sample from the digestion vessel and transfer the digested sample to an analysis system.
