Knowledge and sourcing

Quality and testing

What analysis can tell you, and what it cannot.

This circle is the technical companion to the sourcing circle. It is about the analysis itself: what HPLC measures, what mass spectrometry confirms, why an endotoxin panel is a different question from purity, and the uncomfortable fact that a good number on a document tells you about the sample that was tested and not about the vial in your fridge.

Several members are chemists and they correct the facilitator regularly, which is how it should work.

Who this circle is for

  • You want to understand the analytical methods
  • You have had material independently tested
  • You work in analytical chemistry and can explain things

Agreements here

  • Technical claims get a method attached or they get questioned
  • No test result is used to endorse a supplier
