Determination of Metal Ion Contents in Nanomaterials Solution Using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS): Nano Risk SOP-P

摘要

The presence of metal ions from either metal catalyst or contamination in nanomaterial solutions could directly impact the product quality, such as sensor performance. Inductively coupled plasma-mass spectrometry (ICP-MS), one of the most sensitive analytical techniques used for trace multi-element detection, has become a common tool in many laboratories for determining the metal impurities in various types of samples. This scientific operating procedure (SOP) describes the operation and use of ICP-MS to determine trace metal concentrations in nanomaterials solutions. Procedures and recommendations of sample preparation, instrument preparation, sample analysis and results analysis are included. The procedure has been tested on a variety of carbon-based nanomaterial solutions.
