The most important tool for molecular characterization of synthetic polymers is High-performance liquid chromatographic (HPLC) methods. Mean molar mass (MM) and molar mass distribution (MMD) of linear and branched homopolymers is easily determined by gel permeation (size exclusion) chromatography (GPC/SEC). GPC/SEC provides several other useful data such as limiting viscosity numbers, constants of viscosity law, sizes of macromolecules in solution - and even extent of preferential solvation of polymers in mixed solvents. Recent progress in GPC/SEC comprises improved instrumental hardware and data processing procedures. High sample throughput of the ultra-fast GPC/SEC enables acceleration of analyses, which is especially important in combinatorial material chemistry and in production control. Still, further improvements of the SEC method are needed, which include its hardware, especially columns and detectors, standardization of sample preparation, measurement and data processing. GPC/SEC exhibits excellent intra-laboratory repeatability, which evokes a notion of its high reliability. Recent series of the round robin tests, however, revealed surprisingly poor inter-laboratory reproducibility of results. Evidently, an accuracy of many GPC/SEC results may be rather limited. In most cases, GPC/SEC does not enable precise molecular characterization of complex polymer systems, which possess more than one distribution in their molecular characteristics. Typically, polymer mixtures, copolymers and functional polymers exhibit beside MMD also distribution in their chemical structure. To assess the above distributions, new HPLC procedures are developed. These are based on the controlled combinations of entropic (exclusion) and enthalpic (interaction) retention mechanisms within one column or in a series of independent separation systems. These approaches are denoted “coupled polymer HPLC” and “two- or multi-dimensional polymer HPLC”, respectively. Enthalpic retention mechanisms in HPLC of synthetic polymers include adsorption, partition, phase separation. We shall review recent progress and problems in GPC/SEC, as well as in the couple and two-dimensional polymer HPLC procedures and outline anticipated future development.

Academia has always used analytical techniques to characterize, test, and further promote the outcome of their respective research. Industry, on the other hand, has primarily utilized analytical science as a forensic tool to help solve product and/or process issues. Each endeavor has merit, and definitely is needed, especially in their respective genre. Each physical laboratory is constructed with these types of needs in mind. The Academic laboratory usually contains the equipment required to perform these analytical functions, since it is so central to their project work. Whereas, most industrial laboratories have a completely separated analytical department/lab area due to the fact that their major function is in support of the sales and/or manufacturing arm of the company.
These two endeavors need to be better aligned, such that industry can learn from Academia the importance of analytical sciences to build robust formulations/products during the development phase in order to eliminate the potential for problems after product launch. This will also allow for the building of a better understanding of the structure/property relationship.
