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.
