Abstract
The invention provides differential refractive index detectors and methods for the use of differential refractive index detectors. In an exemplary embodiment, a differential refractive index detector includes a flow cell body having a proximal end, a distal end, and a flow axis extending between the proximal and the distal end. The flow cell body includes a first chamber and a second chamber and the fluid conduits coupled to the flow cell body can be tapered to reduce dispersion.
