Title:
FLOW CELL FOR DIFFERENTIAL REFRACTIVE INDEX DETECTION
Document Type and Number:
Japanese Patent JP2017223690
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a flow cell for differential refractive index detection that can contribute to improved fluid velocity profiles and offer an overall volume that is smaller than conventional flow cells.SOLUTION: A flow cell 100 includes a transparent body 110 extending from a first end to a second end along a longitudinal axis. The transparent body defines a sample prism chamber 118 and reference prism chamber 120. The sample prism chamber is configured to allow fluid to 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 136 comprising a plurality of grooves 140 extending along the longitudinal axis in the direction of the fluid flow.SELECTED DRAWING: Figure 3B
