Size Exclusion Chromatography of Poly(2-ethyl-2-oxazoline) Homopolymers and Poly(ethylene oxide)-b-Poly(2-ethyl-2-oxazoline) Copolymers
… by SEC using multiple detectors. Both a universal calibration method and light scattering were used to determine molecular weights and molecular weight distributions. The solvent was N-methylpyrrolidone that contained 0.05M LiBr used to minimize interactions among the polymers and …

Dilute solution studies of molecular weight distributions of nitrocellulose, modified lignins and PMMA graft polymers
… of long chain branching were found to obey the universal calibration analytic scheme of GPC.

Novel high performance thermosetting polyimides
… determined by gel permeation chromatography (Universal Calibration). Successful molecular weight control was achieved using the reactive endgroups with imide oligomers synthesized with <Mp> values of 2,000 to 15,000 g/mole. The phenylethyny] and phenylmaleic endgroups permitted sufficient flow …

The atom field ion microscope: Fundamental principles of operation
… theoretically and experimentally. A universal calibration procedure for relating the measured flight times to actual mass-to-charge ratios is established. This simple procedure, independent of the Atom Probe's particular operating parameters, only requires measurement of the applied …
