## A calculation procedure is proposed which allows low-angle laser light-scattering measurements to be used as a practicable method for calibration-free molecular weight determinations of soluble coal derivatives. Application of this method to coal solutions allows thermodynamic parameters for t
A number of procedures have been investigated for the calibration of a size-exclusion chromatography (s.e.c.) column in the determination of molecular mass (MM) distributions of coal derivatives. The behaviour of narrow fractions of coal extracts in the MM range 2003000 was compared with a variety o
