Abstract

A method is disclosed for characterizing a plurality of non-biological polymer samples. The method includes the steps of injecting a first non-biological polymer sample into a mobile-phase of a liquid chromatography system, chromatographically separating at least one sample component of the injected first sample from other sample components thereof in a chromatographic column, detecting at least one property of the separated sample component of the first sample, injecting a second non-biological polymer sample into the mobile-phase of the liquid chromatography system while advancing the first sample to the chromatographic column, chromatographically separating at least one sample component of the injected second sample from other sample components thereof, and detecting at least one property of the separated sample component of the second sample.
