Do you know the answers?

Sample concentration

What happens if the sample concentration is too high?

GPC/SEC with concentration detectors does not require accurately known concentrations. But what happens if the concentrations are too high?

  1. Nothing happens, I still get correct molar masses.
  2. The peaks are shifted to higher elution volumes and I get lower molar masses.
  3. The peaks are shifted to lower elution volumes and I get higher molar masses.

Peak shoulders

Why is there a shoulder in my peak?

Broad peaks, sometimes showing several maxima, are quite common in GPC/SEC. But what is the reason for the shoulder in this picture?

  1. Pore size mismatch.
  2. Exclusion, the stationary phase pores are too small.
  3. Aggregation, the chromatographic conditions should be optimized.

Branching

Is my sample strictly linear or is it branched?

Branching influences the macroscopic properties of materials. Which GPC/SEC detection option allows to measure short-chain branching of polyolefins?

  1. GPC/SEC with multi angle online light scattering detection.
  2. GPC/SEC with online viscometry detection.
  3. HT-GPC with IR detection (dual detection).

Answers

Corrects answers:

  • concentration: 2, more pronounced for higher molar masses
  • peak shoulders: 3, in this case aggregation caused the problem
  • branching: 3, you can use dual detection IR detection to learn more about branched polyolefins

Learn more about the technical terms and get background information to the right answers e.g. in our 2day "GPC/SEC Theory and Practice" course.
