A quantitative measure of interaction between polymer and monomer in solution can be expressed by a value of preferential solvation. Preferential solvation can be calculated from the measurements of refractive index increments in dialysis experiments. This experiment can be illustrated as in Figure 3.1. 

Kl can be calculated from dialysis experiments. However, it was demonstrated that there is a large error in the calculation of Kl from the refractive index increments. 

Where (dn/dc)k is the polymer refractive index increment in the solvent mixture, dn/dk is the variation of the refractive index of the solvent mixture as a function of volumetric composition and (dn/dc) is the polymer refractive index increment after establishing dialysis equilibrium. 

Nutritional screening is recommended in dialysis patients.Such screening may involve subjective global assessment, measurement of the body mass index, a recent...

Unlike direct reference assays, indirect index methods use two separate tests to estimate the free hormone concentration a total serum T4 (or T3) measurement and an assessment of either the serum TBG concentration or the fraction of T4 (or T3) that is free m serum the latter is traditionally derived using equilibrium tracer dialysis or T uptake methods. Results of these tests are then combined mathematically to give estimates of the free hormone concentration. Indirect index-based methods have essentially fallen out of favor in deference to the direct immunoassay methods.
