Product info
Working principle of ICP-AES650 spectrometer
ICP-AES650 Inductively Coupled Plasma Emission Spectrometer, also known as ICP Spectrometer ( Inductive Coupled Plasma ), uses inductively coupled high-frequency plasma as the excitation light source, and uses the atomic or ion emission characteristic spectrum of each element to determine the composition of the substance. Qualitative and quantitative analysis of elements. Also known as ICP atomic emission spectrometer. The atomic emission spectrometry analysis process is mainly divided into three steps, namely excitation, spectroscopy and detection.
