  • Combined UV/Vis-absorption and conductivity flow cell for liquid chromatography
    Patent number: 11422117
    Abstract: A flow cell for a detector in a liquid chromatography system includes a flow cell body, an inlet, an outlet, at least two windows situated on opposing sides of the flow cell body, which are transparent for light, and at least two electrodes configured for a conductivity measurement. A detection channel is formed within said flow cell body, fluidly connecting said inlet and outlet, includes an optical path situated in between said two windows such that a light absorption measurement may be performed for a liquid passing through the detection channel, and a conductivity path formed by at least partially drilling through said electrodes to allow for a physical contact of a liquid passing through the detection channel. A detector or liquid chromatography system including such a flow cell as well as uses of the flow cell, detector or liquid chromatography system are also described.
