    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 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: 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.

    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.
