Application of thermospray flame furnace atomic absorption spectrometry for investigation of silver nanoparticles
© 2017, Springer-Verlag Berlin Heidelberg. Thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) was applied to investigate the time-dependent absorption peak profile of various forms of silver.

Thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) was applied to investigate the time-dependent absorption peak profile of various forms of silver.
