Postnova Analytics have published an application study detailing how the technique of Field-Flow Fractionation-ICP-MS can be used to study the size and chemical composition of tattoo ink nanoparticles. According to a recent report from the European Commission Joint Research Centre** - whilst some 12% of Europeans have tattoos, little is known about the long term effects of the chemicals in the inks. Commonly tattoo inks contain metallic impurities that can result in adverse skin reactions, including infections and allergies, right after tattooing or even years later.
