Portable system for heavy metals detection based on spectral analysis

Abstract

The current work presents a miniaturized, capacitive coupled plasma micro-torch equipment used for simultaneous multielemental analysis. The equipment is used in environment and foods control. The equipment is composed of: an RF generator supplying a resonant transformer for the plasma flame generation, a vaporizer, a microcontroller that controls the plasma generator, a computer which runs a PC interface that controls the RF generator and the vaporizer, a spectrometer for the spectral analysis, battery, inverter and an argon tank.
