Accuracy and Precision in GPC/SEC Measurement Uncertainty

GPC/SEC results and their validity are crucial in many applications such as QC/QA testing for product release, registration and accreditation. Determination of result uncertainty can help to select tolerance criteria during method development and validation. This webinar shows how software can help to determine the result uncertainty automatically.

GPC/SEC SYMPOSIUM 2017

October 2-5, 2017

New Orleans, Louisiana

The International Symposium on GPC/SEC and Related Techniques is designed for users from all backgrounds and abilities involved in polymer characterization. Over the course of three days, participants will discuss current analytical challenges in today’s industrial laboratories, learn what support is available from vendors and the academic community, and gain an insight into research that is helping to shape analytical technologies of the future.

 

SESSION TOPICS

Current Industry Challenges

Discuss the challenges faced in routine implementations of GPC/SEC in today’s industries, starting with single detectors but ending with more advanced.

Technology Perspective

Presenters should be in academia or industry and offer current solutions to satisfy industries challenges through delivering deeper understanding and improved analytical solutions.

Solving Complex Analytical Problems

Discuss more complex analytical problems in polymer analysis. Introduce novel solutions and work being done pushing the boundaries of analytics in this challenging area.

Pullulan ReadyCal Kits for GPC/SEC calibration

The calibration of a GPC/SEC-system is a time-consuming process as it requires the accurate weighing of a larger number of different molar mass reference materials for every single calibration. PSS ReadyCals allow for the rapid preparation of reproducible calibration curves without the inconvenience of individually weighing the standards. Just add solvent directly to the ReadyCal autosampler vials filled with a pre-weighed mixture of high quality reference materials with precise concentrations and molar masses.

New in the PSS ReadyCal family are the Pullulan ReadyCals:

• Reference Material: Pullulan

• Application: Calibration of aqueous GPC/SEC systems

• Sets:

Standard: 3 x 5 Vials-1.5ml, Mp 180 – 708 000 Da (11 standards)

or

High 3 x 5 Vials-1.5ml, Mp 180 – 1 220 000 Da (12 standards)

The kits can be used for conventional and for universal calibration (on-line viscometry). The concentrations are also optimized triple detection.

New PSS e-book Series

Part 1: GPC/SEC Theory and Background

PSS e-book Series part 1: GPC/SEC Theory and Practice

Since 2007 PSS has published GPC/SEC Tips & Tricks in LC/GCs digital magazine “The Column”. Many readers collect these publications and have approached us to create a compendium with all the information published in more than 60 editions in over 10 years.

 

To have all published topics at-a-glance, PSS decided to create a series of five different e-books

  •  GPC/SEC Theory and Background
  •  GPC/SEC Columns
  • GPC/SEC Detection
  • GPC/SEC Troubleshooting
  • GPC/SEC Applications

Each book is based on 5-7 different Tips & Tricks publications updated with the latest information, new examples and figures. In addition links to other PSS resources were added, which provide more information to this aspect.

Liquid Adsorption Chromatography Seminar April 2017

PSS USA Inc. will be presenting a seminar on Liquid Adsorption Chromatography in Amherst, MA on April 11th, 2017.

 

This course is aimed at all scientists who are looking for complementary characterization methods and want to learn more about the composition of complex polymer systems. The macroscopic properties of modern high-performance polymers cannot be assessed by the molar mass distribution alone. Many products are copolymers which, in addition to the molar mass distribution, also comprise a composition distribution. Furthermore, branching and end groups are often introduced in order to create high quality products. 

Chemists are facing the challenge of selecting the appropriate characterization techniques for such complex polymer systems. With separation based only on the molecular size, it is impossible to obtain the required detailed information about the sample composition, even if advanced detection techniques are applied. Separation techniques based on composition complement and add value to the existing method tool set.

 

The theoretical background for different interaction chromatography methods for polymers and the achievable information based on the applied technique will be discussed. Practical information on column, solvent and detection selection is given. A compact overview of the coupling of interaction chromatography with GPC/SEC to perform 2-dimensional (2-D) chromatography rounds off the event.
