Today I spent the morning reading several articles on osmotic pressure. I am trying to get a better idea of the results I should expect from the new PEG series I am running. In these tests, the main variable that we will be testing is osmotic pressure. The best idea that I can build as of now is that osmotic pressure has to do with the concentrations of solutes in a solvent. It has several different definitions, depending on the context in which it is being used. The one that seems most relevant to our work is the energy density of solvent molecules. The idea that I am getting is that PEG takes up space in solution that used to be available to water.
I spent the afternoon running my three dilute series after the nitrogen arrived. I will be able to analyze these tomorrow.
