Abstract
Aprakstīta analīzes metode, lai kvantitatīvi noteiktu Cr, Cu, Zn, Mn, Cd un Ni saturu silīcija lietņu paraugos, priežu skuju references materiālā PN SRM 1575 un kaulu references materiālā Bone meal SRM 1486 lietojot dinamiskās reakcijas šūnas induktīvi saistītās plazmas masspektrometrijas metodi (DRC-ICP-MS) pēc paraugu apstrādes mikroviļņu iekārtā. Lai novērstu poliatomiskos traucējumus, šūnā kā reakcijas gāzes ir lietotas metāns un hēlijs. Ar šūnu iegūtie rezultāti pārbaudīti analizējot tos pašus paraugus ar ETAAS metodi (Cr, Mn, Cu, Cd, Ni) un LAAS metodi (Cu, Zn).
An analytical method is described for the quantification of elements (Cr, Cu, Zn, Mn, Cd and Ni) in silicon ingot samples, pine needle reference material PN SRM 1575 and bone meal SRM 1486 using dynamic reaction cell inductively coupled plasma mass spectrometry (DRC-ICP-MS) after microwave digestion. Methane and helium were used as reaction collision gases to reduce polyatomic interferences. DRC data were verified by analyzing the same samples with ETAAS (Cr, Mn, Ni, Cu, Cd) and FAAS (Cu, Zn) methods.
