Vapor phase osmometry (VPO), also known as vapor-pressure osmometry, is an experimental technique for the determination of a polymer's number average molecular weight, Mn. It works by taking advantage of the decrease in vapor pressure that occurs when solutes are added to pure solvent.
How does an osmometer work?
The osmometer uses the solution's freezing point depression to establish its strength. It is used to determine the level of osmotically appropriate body fluid in various chemicals dissolved in the blood using the relationship which a mole of dissolved substance reduces the freezing point of water by 1.86 °C (35.35 °F).
What are osmometer cells?
An osmometer is a device for measuring the osmotic strength of a solution, colloid, or compound. ... Membrane osmometers measure the osmotic pressure of a solution separated from pure solvent by a semipermeable membrane.
