Agilent PL-GPC 50 Plus Poly(styrene-co-butadiene) GPC Application Note
This document details the analysis of styrene/butadiene rubber copolymers using gel permeation chromatography (GPC) with viscometry. It explains that while light scattering is unsuitable for these copolymers due to non-uniform chemistry, the Universal Calibration technique using a viscometer provides accurate molecular weight distributions independent of column standards.
The analysis was performed on an Agilent PL-GPC 50 Plus integrated system equipped with a differential refractive index detector, an Agilent PL-BV AQ0RT viscometer, and PLgel 5 pm MIXED-C columns. The results demonstrate the system's ability to resolve molecular weight distributions and determine material structure for elastomeric materials.

Questions answered in these manuals
Why is viscometry used instead of light scattering for these samples?
Light scattering cannot be used because the samples are copolymers with non-uniform chemistry, which leads to errors in calculations.

What advantage does the Universal Calibration technique offer?
It gives molecular weight that is independent of the standards used in the column calibration.

How was the structure of the cornflour samples compared?
The structure was compared using the Mark-Houwink plot of log (intrinsic viscosity) as a function of log (molecular weight).
