Abstract: An ultrapure water (UPW) generation and verification system can include a cleaning chemical station, a cleanup column, a conductivity verification station, and a holding reservoir, in fluid communication with one another. The cleaning chemical station can be configured to selectably permit a flow of water to pass therethrough to the cleanup column or to block the flow of water and instead deliver a cleaning chemical to the cleanup column. The conductivity verification station can be configured to selectably perform at least one of the following: permit water to flow from the cleanup column to the holding reservoir; direct fluid to waste; or test the conductivity of the water for a purity level.

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 fluid handling assembly for selectively coupling and decoupling with a pipet tip can include a sampling arm, an arm cover, a probe carrier unit, a probe, and a biasing spring. The arm cover can be carried by the sampling arm. The probe carrier unit can be movably mounted within the arm cover, with the probe carrier unit including a probe release structure and a main probe carrier. The probe release structure and the main probe carrier can be interconnected. The probe can be carried by the main probe carrier and movable through a probe opening in the arm cover. The probe can be configured to releasably carry a pipet tip. The biasing spring can be carried within the arm cover and can contact the probe release structure. The biasing spring can bias the probe release structure to push the probe down toward the probe opening in the arm cover.
