Chemistry; Analytical chemistry
Procedure for analysis of complex chemical mixtures by the progressive absorption of the components of the unknown sample (in a solvent) on a special grade of paper.
cryoscopy
Chemistry; Analytical chemistry
A phase-equilibrium technique to determine molecular weight and other properties of a solute by dissolving it in a liquid solvent and then ascertaining the solvent’s freezing point.
vapor-pressure osmometer
Chemistry; Analytical chemistry
A device for the determination of molecular weights by the decrease of vapor pressure of a solvent upon addition of a soluble sample.
