Quantitative separation of polystyrene nanoparticles in environmental matrices with picogram detection limits using capillary electrophoresis†
Abstract
We developed a capillary electrophoresis method to separate polystyrene particles (PSPs) with different sizes or different surface functionalities. Separations were performed in buffer and 100 mg Lā1 clay or 100 mg Lā1 Suwanee River humic acid. In all solutions, PSPs were baseline or near-baseline resolved in less than 15 minutes.
