Mineral oil in infant formulas - guidelines for integrating chromatograms
JRC IF 2021-04: a virtual inter-laboratory comparison
Mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) consist of a mixture of various hydrocarbons that are difficult to resolve in a chromatographic column. They produce complex unresolved chromatographic signals (called humps). The quantification of total MOSH and total MOAH mass fractions requires proper integration of the respective humps, after background subtraction and the removal of the remaining interfering peaks. Such an operation is prone to subjective judgement that may increase the scatter of reported results.
The European Union Reference Laboratory for Food Contact Materials (EURL-FCM) organised the first virtual interlaboratory comparison (e-ILC) "JRC-IF-2021-04" to assess the capabilities of the participants in “integrating chromatograms of mineral oils in infant formulas (IF)”.
A set of chromatograms in “cdf” (binary) or “csv” (ascii) formats - related to IF samples, hexane baselines, and retention time calibrations - were provided to the participants. They were requested to submit results for the mass fraction of total MOSH and total MOAH in seven IF samples.
