P2206-MRT

MOSH/MOAH in cheese (GCxGC-TOF-MS)

P2206-MRT is designed to fit to the requirements of the analysis of MOSH/MOAH by GCxGC-TOF-MS.

Two spiked/contaminated samples of cheese are provided. The cheese is spiked with a selection of the substances mentioned below.

The aim of the method ring test is the correct identification of

  • different types of MOSH (alkanes, cycloalkanes, hopanes, steranes, waxes, POSH, PAO, ROSH etc),
  • different types of MOAH (aromatic ring systems, alkylated aromatic systems, etc.)
  • marker substances like hopanes, DIPN, etc., as well as
  • typical contaminations with waxes etc.

The participants are asked to report

  • whether or not the substances (groups) are identified in the provided test sample.
  • a chromatogram, which shows the different groups of MOSH and MOAH. The different groups of MOSH and MOAH should be marked and allocated in the chromatogram.
  • details related to the applied analytical method in a questionnaire.
