AN2604: Characterization of Gold Nanoparticles with AF4-ICP-MS

Eclipse AF4

In this study, a mixture of gold nanoparticles was characterized via AF4-ICP-MS coupled to single-particle-inductively coupled plasma mass spectrometry (sp-ICP-MS). This approach is able to monitor changes of particle size distribution and recovery caused by variation of ionic strength in the carrier solution of the separation. The analysis yields valuable information on the particle size and the aggregation behavior of a suspension at different ionic strengths.
