P2303-MRT is designed to fit to the requirements of the analysis of MOSH/MOAH by GCxGC-TOF-MS.
Two spiked/contaminated samples of coconut oil or fat are provided. The samples are spiked/contaminated 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.
