MOSH/MOAH in spelt (LC-GC-FID, GCxGC-FID, ring systems)

Analysis of MOSH and MOAH by LC-GC-FID is a routine technique nowadays, while the analysis by GCxGC-FID is more advanced and is applied for quantification of MOAH separately for the different ring systems.

P2704-MRT offer laboratories the choice to quantify the material

by LC-GC-FID for total MOSH and total MOAH, and/or
by GCxGC-FID for MDAF (mono- and diaromatic fraction) and TPAF (tri- and polyaromatic fraction), and total MOAH according to their needs.

A full validation of both analytical methods cross the techniques is possible if both modules are chosen.

Attention: Please make sure that you choose the correct technique for your lab and your instrumentation!

A spiked sample of milled spelt (flour) and the corresponding unspiked milled spelt are provided as test material and blank material.

An LOQ of total MOAH of 0.5 mg/kg is required in accordance with the expected maximum levels.
