A New Desolvation System for Use with Capacitatively Coupled Microwave Plasma and Inductively Coupled Plasma-Atomic Emission Spectrometry

Abstract

A compact and highly efficient desolvation system with a pneumatic nebulizer was applied to capacitatively coupled microwave plasma and inductively coupled plasma-atomic emission spectrometry. Approximately 50% of the analyte (Mn) was introduced to the plasma, and 50 (CMP) and 16 (ICP) times improvement of the sensitivity could be achieved. In spite of slightly poorer stability caused by larger aerosol size, detection limits were 17 (CMP) and 10 (ICP) times superior to results achieved with conventional pneumatic nebulization.
