                   Project objective:

In spite of the ample use of Size Exclusion Chromatography (SEC) for measuring the molar mass distribution (MMD) of polymers, there are huge variations in the results by different laboratories, when analyzing the same polymer sample. One of the possible reasons for such variations may be the applied data treatment. Thus, it seems indispensable to standardize the SEC data treatment.

The IUPAC Mission is “to provide leadership, facilitation, and encouragement of chemistry, promoting the norms, values, standards, and ethics of science and the free exchange of scientific information”. The standardization of the SEC data treatment through a prestigious and non-profit organization such as IUPAC seems the ideal solution for producing more uniform and accurate MMD estimates among the different chemistry laboratories of the world.

Objectives:

1)      Develop a robust and practical correction for band broadening (BB), with the aim of improving the accuracy of the measured MMD and other polymer molecular characteristics.

2)      Quantify and correct for other systematic sources of error in the SEC data processing.

3)      Compare and evaluate the different classical and novel data treatment methods, with the long-term aim of recommending a standard procedure that may be useful for general SEC users and instrument manufacturers.
