AGQM_icons_rgb_Ringversuch.jpg International Round Robin Test ‚Pharmaceutical Glycerol‘

Apart from Fatty Acid Methyl Ester (FAME) which is mainly used as fuel (Biodiesel) and must comply with high quality standards, glycerol – a by-product of the Biodiesel production – is also gaining continuously in importance. In the past it was used primarily in the fields of cosmetics and technology but nowadays it is used more and more as high-quality pharmaceutical glycerol which is gained by refining raw glycerol.

With this Round Robin Test glycerol we wish to enable both company laboratories as well as commercial service laboratories to carry out external quality assurance for selected parameters of the analytics of pharmaceutical glycerol.

In the Glycerol Round Robin Test two samples - Glycerol A and Glycerol B - are tested according to

the following selected methods of the current version of the European Pharmacopoeia (EP):

  • Ester Content
  • Density
  • Colour
  • Refractive Index
  • Clycerol Content
  • Sulphated Ash
  • Water Content
  • Determination of Elements
  • Impurity A

Upon finalization of the round robin test, all participants receive a detailed (anonymised) report in German and English as well as certificate (also bilingual) with all their individual results.

We hope to have aroused your interest and would very much like to welcome you also as one of the next participants.
