Abstract
The validity of the universal calibration concept in tetrahydroforan (THF) and in dimethylacetamide (DMAC) is explored in the low molecular weight reg ion for molecular weights less than 10,000 daltons. A variety of calibrant polymer types and column packings are studied utilizing a single capillary GPC-viscometer (DV)/differential refractometer (DRI) chromatographic system . Use is made of the Sanayei-O'Driscoll-Rudin single parameter universal ca libration model based on K-theta to assess the validity of the universal ca libration concept.
