  • High-pressure fluorescence flow cell, flow cell assembly, fluorescence detector, and supercritical fluid chromatograph
    Patent number: 9267887
    Abstract: A high-pressure fluorescence flow cell comprises a cell body made of a light-transmissive material, wherein the cell body is penetrated by a straight-line flow path for a high-pressure fluid, wherein the flow path is formed with a cross section of 0.1 mm2 to 5 mm2, both inclusive, orthogonal to its longitudinal direction, wherein the ratio t/d of the wall thickness t (mm) to the width d (mm) of the flow path satisfies formula (1) below, t d ? 1 2 × [ ? + P ? - P - 1 ] × 1.5 ( 1 ) where ? indicates the tensile stress (MPa) of the material of the cell body, and P indicates the withstand pressure (MPa) of the cell body.
