Convite para palestra com pesquisador internacional – sexta-feira – 24/03/2023 – Anfiteatro (sala A) FAEM – 14h00

PPGQ – PPGBBio – PPGCTA UFPel convidam para palestra com pesquisador internacional intitulada:

“An introduction to microwave induced plasma optical emission spectrometry (MIP-OES)”
 
A palestra será ministrada pelo Dr. Helmar Wiltsche, da Graz University of Technology, Graz, Áustria.
 
DATA: 24/03/2023 – 14h
LOCAL: Anfiteatro (Sala A) – FAEM
 
RESUMO: Microwave induced plasmas (MIPs) have become widely used in analytical chemistry with the availability of a commercial Hammer cavity instrument. In this lecture the working principles and application of this microwave cavity are discussed. Contrary to inductively coupled plasmas, high-power MIPs, such as found in the Hammer cavity are operated with nitrogen or even air as the sole plasma gas. The implication of using nitrogen as plasma gas will be discussed, as well as inter-element matrix effects. Moreover, a new approach for defying the matrix effects caused by easily ionizable elements is shown.
