The present invention is drawn to an apparatus for continuously measuring physical and chemical parameters in a fluid cell comprising a single flow cell having a fluid interface for conducting the fluid through the flow cell, an electrical interface connected to at least one first means provided in the flow cell wall for measuring at least one first parameter of the fluid in the flow cell, and an optical interface for transmitting light into the flow cell and for receiving light from the flow cell to measure at least one second parameter of the fluid in the flow cell.

Apparatus for continuously measuring physical and chemical parameters in

Method and apparatus for determination of refractive index

The microfluidic structure comprises first and second substantially planar form-stable base layers and an intermediate spacing layer of elastic material, said spacing layer being recessed to define a microcavity or channel system with at least one of said first and second base layers. The structure is produced by moulding the spacing layer, optionally applied to or integral with a first base layer, against a planar mould, and the microcavity or channel system is completed by applying a second base layer, and optionally said first base layer, to the spacing layer.
