摘要： A method and apparatus are provided for the measuring osmotic pressure of a solution. A sample of a solution is placed into a sample cell above a membrane supported in the sample cell and the sample cell is sealed. Gas at an elevated pressure is introduced into the sample cell to drive a quantity of dialyzate through the membrane and into a transparent dialyzate exit tube adapted to receive the dialyzate which passes through the membrane. The elevated pressure of the gas is varied through a pressure regulator to yield a substantially stationary dialyzate meniscus in the transparent dialyzate exit tube. The pressure in the sample cell is measured by reading a pressure gauge showing the elevated pressure of the gas that yielded the substantially stationary dialyzate meniscus, the elevated pressure of the gas being substantially equivalent to the osmotic pressure of the sample.

摘要： A particle diffusion coefficient measuring device is provided with a hollow-fiber including micropores on its surface. The hollow-fiber provides a passage for particle suspension to transport through. The device is also provided with a fluid passage formed outside the hollow-fiber to communicate with the hollow-fiber via the micropores. The fluid passage provides a passage for an electrolyte solution to transport through in such a manner that the electrolyte solution is delivered to flow in the same direction as that of the particle suspension and is discharged from the fluid passage. The device detects a concentration change of the particles in the electrolyte solution discharged out of the fluid passage over a time change and calculates a particle diffusion coefficient by using the concentration change of the particles over the time change.

摘要： A method is provided for determining the concentration of a solution having a predetermined osmotic pressure and/or for generating a solution with a predetermined osmotic pressure. The method is performed by placing a sample of a solution into a sample cell, the sample cell including therein a membrane supported therein; sealing the sample in the sample cell; introducing gas at a predetermined elevated pressure substantially equal to the predetermined osmotic pressure; and generating a dialyzate by allowing the solution to dialyze through the membrane until equilibrium is achieved and no more dialyzate passes through while the sample cell is maintained at the predetermined elevated pressure, the sample remaining in the sample cell having an osmotic pressure substantially equal to the predetermined elevated pressure; collecting the dialyzate of said generating step; and weighing the dialyzate of said collecting step to determine the concentration of the solution remaining in the sample cell.
