Differential refractometers contain a flow cell with two parts : one for the sample and one for the reference solvent.
2.
It was a benchtop system equipped with a Milton Roy pump, syringe injection, and two detectors : a Waters differential refractometer and a UV detector from the Laboratory Data Control ( LDC ) Co.
3.
The refractive index increment " dn / dc " characterizes the change of the refractive index " n " with the concentration " c ", and can be measured with a differential refractometer.
