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 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: A method for detecting material in a sample using an ICP instrument includes preparing the sample for analysis by the ICP instrument using hydrogen gas. For example, hydrogen gas can be generated by initiating a hydride generation reaction with the sample. Further, hydrogen gas can be introduced to a component part of the sample. For instance, hydrogen gas can be added to an injector gas in a spray chamber of the ICP instrument.

Abstract: A system can include a sampler assembly configured to collect a viscous sample at a first location. In implementations, the viscous sample includes concentrated sulfuric acid (e.g., greater than about 75% H2SO4). The system can also include a valve coupled with the sampler assembly for receiving the viscous sample. The valve is configured to couple with a source of a diluent and a sample transfer line. The system further includes a pump coupled with the valve for injecting the diluent into the sample transfer line along with the viscous sample to dilute the viscous sample and transport the diluted sample to a second location remote from the first location via the sample transfer line. In implementations, the sample transfer line is at least approximately two meters in length.

Abstract: A dampening device for an automated sampling/dispensing device is described. In an example implementation, the dampening device includes a cylindrical body. The cylindrical body includes a first end and a second end, a first opening being defined within the first end and a second opening being defined within the second end. Further, the cylindrical body may include an inner diameter greater than an outer diameter of an automated sampling/dispensing device sample probe. During operation, the dampening device moves out of phase with the automated sampling/dispensing device sample probe allowing sample probe vibrations to be dampened during operation. The dampening device is configured to be magnetically attracted to the sampling/dispensing device. For example, the dampening device and/or the sampling/dispensing device can include a permanent magnetic material, a ferromagnetic material, a ferrimagnetic material, and/or an electromagnet.

Abstract: A sample introduction system providing variable online dilution of a sample is described. In one or more implementations, the sample introduction system includes a sample pump configured to pump a sample in a specified time interval and a first carrier syringe pump configured to pump a volume of a carrier to be combined with the sample in the specified time interval. A control module is configured to receive a specified dilution level for the sample (e.g., input by an operator) and selectively adjust the volume of the carrier pumped by the first carrier syringe pump in the specified time interval to furnish the specified dilution for the sample.
