A simple model of spherical molecules in cylindrical pores has been used to show that the shape of GPC calibration curve is quite insensitive to the width of the pore-size distribution of the porous packing.

A new method is proposed for determining the spreading factor h(v) in the Tung integral equation, based on moment analysis of original (uncorrected) and corrected, normal-flow chromatograms of calibration standards. The reliability of the new procedu

Two different ways of accelerating analyses of glucose oligomers by reversed-phase chromatography and of improving their sensitivity are presented. A specially developed glass cartridge packed with a C 18 bonded silica of the Separon type was used fo

A method of zone spreading correction in gel permeation chromatography is described that is applicable in the case of a Guassian-type spreading function. Instead of the integral Tung equation, an equivalent partial differential equation is solved num

A partial differential equation has been derived that describes the non-steady-state pressure profile along a chromatographic column for the case of a liquid mobile phase of finite compressibility. This equation was solved subject to boundary conditi

The growth center in the anionic polymerization of methacrylic esters is stabilized with alkaline alkoxides, sodium tert-butoxide in particular. The lifetime of the growth center was investigated in the polymerization of methyl methacrylate by evalua
