Patent number: 10151686Abstract: A flow cell for differential refractive index detection. The flow cell includes a transparent body that extends from a first end to a second end along a longitudinal axis. The transparent body defines a sample prism chamber and reference prism chamber. The sample prism chamber is configured to allow fluid flow between the first and second ends of the transparent body along the longitudinal axis. The reference prism chamber is configured to receive a reference fluid. The sample and reference prism chambers each include a grating comprising a plurality of grooves extending along the longitudinal axis in the direction of fluid flow.Type: GrantFiled: August 16, 2012Date of Patent: December 11, 2018Assignee: WATERS TECHNOLOGIES CORPORATIONInventor: Anthony C.

Patent number: 5402241Abstract: Radiant energy is transmitted to a probe element including an interior conical reflecting surface and a fluid sample chamber. Portions of the light which have been transmitted, partially attenuated, or scattered by a fluid sample in the sample chamber are directed by at least a portion of the interior conical reflecting surface to means for collecting the transmitted, partially attenuated, or scattered light. A stilling valve incorporated into the probe element enables elimination of entrained gas bubbles from the chamber.Type: GrantFiled: October 15, 1991Date of Patent: March 28, 1995Assignee: The Foxboro CompanyInventors: Anthony C.
