OSMOTIC PRESSURE BAROMETER

van't Hoff discovered and quantified the phenomenon known as "osmotic pressure". I wonder what are the limitations on osmotic pressure....what is the highest osmotic pressure possible. It is a pressure based on the concentration of particles in solution. The nitrate salts form the highest concentration solutions possible. One would need to construct an osmotic pressure barometer to "measure" very high osmotic pressures. I have suggested an osmotic pressure barometer but it is only a theory. The description was in what was barely a paper in the Annals of the Scientific Society of Argentina. I did not have a chance to improve the manuscript before they published it.
