T1  - 70 years size exclusion chromatography - An ongoing challenge
N2  - The reason for our current activities is that polymers may also be subject to REACh regulations in the future. In this context, the determination of oligomer content is important.
SEC is still the method of choice for determining molar mass distribution. The regulations aim for narrow limits and SEC has rather large error margins, which are well known to all experts. Different polymers need different methods. What to do when samples with a wide range of practical aspects, samples with higher distribution range, reduced solubility, including side components, gel content etc. need be analyzed?
A concept for round robin tests and first impressions will be presented.
