MOSH/MOAH in infant formula (identification, GCxGC-TOF-MS)

P2406-MRT is designed to fit to the requirements of the analysis of MOSH/MOAH by GCxGC-TOF-MS (identification of typical components of MOSH/MOAH and related substances!).

A contaminated sample of infant formula is provided. The sample is 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.

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.


n-alkanes, iso-alkanes, multi-branched alkanes, cycloalkanes, hopanes, steranes, phytane, pristane, POSH, PAO, wax, ROSH, alkylated benzenes, alkylated naphthalenes, alkylated anthracenes, alkylated benzanthracenes, 2-ring MOAH, 3-ring MOAH, 4-ring MOAH, 5-ring MOAH, 6-ring MOAH, DIPN, benzothiophenes, ROAH
