Coupling Flow Field Flow Fractionation to ICP-MS for the Detection and Characterization of Silver Nanoparticles

This note presents the versatile size-separation technique of field flow fractionation (FFF). The resultant hyphenated technique of FFF-ICP-MS is shown to provide nanoparticle sizing, detection, and composition analysis capabilities at the parts per billion (ppb) level, which is useful to environmental investigations of nanomaterials.
