Use of Single Particle Inductively Coupled Plasma Mass Spectrometry to Characterize a New Silver Nanoparticle Reference Material

Murphy K.E., Liu J., Guthrie W.F., Gorham J.M., Bonevich J.E., Allen A.J., Winchester M.R., Hackley V.A., MacCuspie R.I., National Institute of Standards and Technology, US

In this study we use a conventional inductively coupled plasma mass spectrometer operated in single particle mode (spICP-MS) to simultaneously characterize the size distribution and dissolved silver fraction of a new candidate silver nanoparticle reference [...]

Optimizing Instrument Operation and Data Processing for Single Particle Inductively Coupled Plasma Mass Spectrometry Measurement of Gold Nanoparticles

Liu J., Murphy K.E., MacCuspie R.I., Winchester M.R., National Institute of Standards and Technology, US

In recent years, inductively coupled plasma mass spectrometry (ICP-MS) operated in time-resolved analysis (TRA) mode has merged as a promising analytical tool capable of both sizing and counting metal containing nanoparticles in aqueous suspensions. In [...]
