Abstract: A system is provided that includes a tray having a number of compartments for holding liquid samples and partitioning the liquid samples from one another. The liquid samples are prepared by adding an indicator configured to produce a characteristic change in light from the liquid samples when a target microbe metabolizes the indicator while the liquid samples are incubated. The system also includes a light sensor for sensing light from the liquid samples held in the tray while the plurality of liquid samples is incubated. The system further includes a processor coupled with the light sensor and configured to analyze the light from the liquid samples while the liquid samples are incubated to detect the characteristic change in light from one or more of the liquid samples if the target microbe is present in the liquid samples.

Abstract: A peristaltic pump includes a rotating member operably coupled to a drive. The rotating member includes a plurality of rollers arranged in a circular configuration. A guide member defines a channel configured to direct a peristaltic tube around the rotating member so that the peristaltic tube interfaces with the plurality of rollers. The peristaltic tube is pressed against the plurality of rollers by a retaining shoe. The retaining shoe contains surface irregularities configured to restrict movement of the peristaltic tube. A keeper braces the restraining shoe against the peristaltic tube. The rotating rollers compressing the peristaltic tube against the retaining shoe as the rotating member rotates results in a peristaltic action that produces a nearly pulse free linear flow.

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: A system includes a sample selector device, a chromatographic column selectively connectable to the sample selector device, and a spectrometry analysis device selectively connectable to the sample selector device. The sample selector device is configured to supply multiple individual samples to the chromatographic column to separate components of the individual samples. The sample selector device is also configured to store the separated components of the individual samples. The sample selector device is further configured to supply the separated components of the individual samples to the spectrometry analysis device. In embodiments of the disclosure, the components of the individual samples can be chromatographically separated while the spectrometry analysis device is offline.

Abstract: This disclosure is directed to a system and method relevant to sampling halosilanes or other water-reactive samples. In embodiments, a system for hydrolyzing samples includes a container with a receiving liquid (e.g., an HF solution) contained therein and an actuator coupled with the container. The actuator can be configured to rotate the container, thereby inducing a vortex in the receiving liquid. The system further includes a sample tube configured to direct a halosilane sample into the vortexed receiving liquid. The sample tube can be oriented to release the sample in a flow direction of the vortexed receiving liquid.
