## Abstract It is shown that an interferenceβpolarizing refractometric detector makes it possible to use microcolumn sizeβexclusion chromatography (MSEC) columns with inner diameters of 0.2 to 0.5 mm and ensures a detection limit (at a signal to noise ratio of 3) of 8 Γ 10^β8^ refractive index unit

β¦ Synopsis
Exclusion chromatography on microcolumns 0.5-1 mm in diameter is an efficient and very economical method of investigating molecular-weight distribution (MWD) of polymers. In fact, the application of columns of 0.5 -1 mm instead of 4 mm in diameter makes it possible to reduce the consumption of sorbent and eluent by a factor of 25-100 thus permitting the use of any solvents, even very expensive ones, under rigorous conditions of toxic and fire safety.
