3M will stop the manufacture of per- and polyfluoroalkyl substances (PFAS) by the end of 2025. This includes Novec™ 7100, also known as HFE 7100. The European Chemical Agency (ECHA) are also considering the restriction of PFAS.
The Fingermark Visualisation Manual recommends HFE 7100 as the carrier solvent for amino acid reagents. As these processes are important in fingermark enhancement laboratories, Dstl are investigating several different options to maintain this capability.
