Abstract

A rapid dynamic osmotic pressure technique is described, which uses a high‐speed small‐volume osmometer equipped with capillaries of small diameter to measure solvent transport rates across the membrane. Measurement of the osmotic pressure of a solution can be made in 10 to 15 min. Comparison of the dynamic results for molecular weight with those obtained by the static‐equilibrium method indicates that the dynamic method affords a much closer approximation to the true number‐average molecular weight than does the static method when membrane‐permeable components are present in the sample.

## Abstract A comparison of dynamic methods for osmotic pressure molecular weight determinations has been made between the authors' method, the recently published method of Elias, and two other commonly used procedures. Samples containing various amounts of membrane‐permeating solute were studied w
