of measurement, as compared to cryoscopy and ebulliometry. 13.4.2
Ebulliometry Like cryoscopy, ebulliometry evolved itself into a useful technique
for the determination of molecular weights of solutes. It is based on a very simple
observation ...

Determination. of. Molecular. Weight. by. Ebulliometry. Myer. Ezrin. Introduction.
Number-average molecular weight can be measured by any method that
measures the lowering of vapor pressure of a solvent due to a solute.1 This
includes ...
For dilute polymer solutions, however, there is continuing application of
ebulliometry as an absolute method for the direct determination of the number-
average molecular mass Mn. Dedicated differential ebulliometers allow the
determination of ...

Occasionally used with polymer solutions for the determination of number
average molecular mass. ebulliometry (ebullioscopy) A technique for the
determination of the molecular mass of a solute, by measurement of its ability to
raise the ...

Measurement of the Thermodynamic Properties of Multiple Phases
An ebulliometer is the main part of a vapour pressure measuring apparatus. In
principle, it is similar to an ordinary open reflux condenser/boiler that operates at
ambient pressure. Ebulliometry is a relatively old technique [18], and as a result,
...

Modern Methods of Polymer Characterization
Cryoscopy generally offers greater sensitivity than ebulliometry and should be
capable, in theory, of accurately measuring molecular weights up to about 50,000
g/mol. Limitations of the method include the tendency for polymer to precipitate ...

Polymer Molecular Weights, (2 Part)
V. EBULLIOMETRY Ebulliometry, one of the classical methods for molecular
weight determination, has undergone many refinements in recent years owing to
interest in the characterization of polymers. The present status is considered in

accuracy of ebulliometry can exceed that for static methods, but it is more difficult
to extend ebulliometry to high pressures. Sometimes comparative measurements
are used, where a substance whose vapor pressure is well known (such as ...
