Abstract: Valve assemblies are described that provide magnetic coupling between a valve actuator and a valve body housing the valve rotor and stator. A valve assembly embodiment, includes, but is not limited to, a valve body, the valve body including at least one magnet, and a rotor and a stator configured to define a plurality of fluid flow passageways; a valve actuator configured to drive the rotor via a drive shaft; and an actuator mount coupled to the valve actuator and configured to magnetically couple with the at least one magnet of the valve body to magnetically couple the valve body and the valve actuator.

Abstract: Automated systems are described that remove a cap from a capped sample container, introduce a probe to the uncapped sample container, direct the sample through the filter to provide a filtrate, and transfer the filtrate to another uncapped sample container, a sample fluid line in fluid communication with a sample analysis system, or combinations thereof.

Abstract: Sample preparation systems and methods for inline autodilution of fluid samples are described. A system embodiment includes, but is not limited to, a filter probe including a probe tube, a probe fluid line, and a filter having an array of through-holes to block particulates present in a fluid sample to provide a filtered sample; a probe valve; a nebulizer valve; a plurality of fluid lines including (i) a sample line and (ii) a dilution line; a pump system; and a controller configured to access sample information associated with the fluid sample to determine a dilution factor for the fluid sample, the controller configured to change the configuration of the probe valve or the nebulizer valve based on the dilution factor to direct, via action of the pump system, the filtered sample into the dilution line prior to the sample line for fluid samples having a dilution factor greater than one.
