PFAS are substances with very variable characteristics; they can be volatile, semi-volatile and non-volatile.
It is therefore necessary to use, in TARGET and UNTARGETED mode, the HS GC-MS, GC-MS and LC-Q-TOF techniques for non- volatile molecules. ECHA confirmed this need for MOCA by publishing an Annex to the PFAS restriction proposals.

For these type of compounds, in order to obtain a valid unturgeted testing, it is necessary to own specific libraries and high definition instruments like the LC-Q-TOF (following the standard CEN / TS 15968 : 2010), which can perform screening based on the exact mass of the molecules.

Food Contact Center has developed a useful library that contains more than 10,000 fluorinated compounds, by using the LC-Q-TOF technique (high definition spectrometer).

The library also contains MS-MS spectra of numerous molecules (EPA 537 list, ADONA, GENX…) for the quantitative targeted analysis.

THIS IS THE FIRST LABORATORY THAT IS CARRYING ON THESE SCREENING TESTS INTO ACCREDITATION,
ACCORDING TO EN ISO 17025, THANKS TO THE KNOW-HOW AND THE LIBRARIES DEVELOPED.
