  • The concentration of the samples exceeded the capacity of the osmometer and therefore were diluted with distilled water (1: 1 or 1: 2 urine: water depending on concentration of sample) prior to the measurement.



Example sentences
  • The osmometric measurement of molecular weight is based on the fact that the osmotic pressure is proportional to the number of gram-molecules of dissolved material in a definite volume of solution.




Example sentences
  • Other methods of molecular weight determination include gel permeation chromatography, end-group analysis, and osmometry.
