Refractometer overview
WebThe differential refractometer signal scales as the concentration, c, of the polymer solute. The viscometer signal is proportional to cMa ( Section 3.3.2 ), with the exponent a about equal to 0.7 for most polymer solutions used in this analysis. The light-scattering signal scales as cM ( Eq. 3-56 ). WebRefractometric sensors can be used for measurements of concentration when analytes of known refractive index are present in simple mixtures in the test medium. Such species should have a constant or independently monitored absorbance and turbidity, in order not to contribute to measurement error.
