A Simple Thermospray System Used in Microwave Plasma Torch Atomic Emission Spectrometry

Abstract

Abstract: An improved thermospray system combined with Microwave plasma torch atomicemission spectrometry (MPT-AES) was proposed.The high pressure pump was replacedwith a peristalic pump, and the appendix heating tube was removed, this improvementmakes the thermospray system more compact and economical.The effects of operation pa-rameters on the emission intensity were studied.Compared with pneumatic nebulization, thedetection limits for Mg and Pb of this system were improved to 5～10 times.And an ele-ment-selected enhancement phenomena was found.

Key words: Thermospray, Microwave plasma torch, Atomic emission spectrometry
