“…Since the applicability of equation [1] for calculating true values of h is in some cases limited by incorrect values of Mw/Mn reported by the producers (13,14), the plot of h against v was determined by means of the procedure proposed by Kotaka (15). The criterion of fitting of the graphically simulated variation of h with v to its real course was the minimum difference between Mw/Mn given by the producer and its value calculated for individual reference PS samples.…”

“…Anomalous results observed with GPC use of an automatic capillary viscometer were traced to zone spreading (85) and led to a method for direct determination of the resolution factor for the separation system employed (88). Grubisic-Gallot et al devised a technique for quantitatively evaluating the axial dispersion term from recycle GPC (76).…”

This review covers the time period of about December 1975 to November 1977. Since we depend on abstracting services in some cases, there is some time overlap with the period covered by the last review (73). The literature surveyed for this review included major analytical, chromatography, and polymer journals, as well as various abstracting services. We've included literature on size separation from soft gels ("gel filtration"), semi-rigid gels ("GPC"), and porous, inorganic column packings ("rigid gels"). And we've reviewed size separations involving small molecules as well as work restricted to macromolecules. We continue to use the common abbreviation, GPC, for gel permeation chromatography applications involving all the above areas. The more definitive "steric exclusion chromatography" is, however, still preferred nomenclature. GENERAL REVIEWSA number of books published during this period included one or more sections on theory and use of steric exclusion chromatography (28,55,152,174,176). Several review articles also included general GPC information. Abbott (1) and Miller (129) discussed elementary operating principles and usefullness for polymer analyses. Krauss and Krauss reviewed theory and practice of both thin layer and column GPC (105). Current status of aqueous GPC was reviewed by Cooper and

The theoretical principles of the method are summarized in 25 equations, resulting from t h e application of the ITtheorem t o the calibration of the sedimentation coefficientmolecular mass and abscissa of the gel-permeation chromatogrammolecular mass relations. Turbidimetric titration was considered. Only t w o independently determined moments, e.g. Bw and H,, are needed for the calibration. The method was developed for investigations in preparing new polymers. Die Anwendung des Ii-Theorems zur Bestimmung der Molekiilinassenoerteilung in individuellen unfraktionierten Polymerproben. I . Theoretische GrudlagenDie theoretischen Grundlagen des Bestimmungsverfahrens werden in 25 Gleichungen angegeben. Die Gleichungen wurden aus der Anwendung des 17-Theorems auf die Eichung der Beziehungen zwischen Sedimentationskoeffizient und Molekiilmasse sowie zwischen der Abszisse des Gelchromatogramms und der Molekulmasse abgeleitet. Die turbidimetrische Titration wird betrachtet. Nur zwei unabhiingig bestimmte Momente, z. B. zw und z,,, sind fur die Eichung notwendig. Die Methode wurde fur Untersucbungen bei der Entwicklung neuer Polymere ausgearbeitet. IIp w n e n u e n-meopewiIE onpetleaenurn Nonexyaspnomaccoeozo pacnpetlemnus e otlunornbsx npo6ax nomrepoe I I .
