Inductively Coupled Plasma Emission Spectrometer
Introduction
Inductively coupled plasma emission spectrometer,as a professional laboratory analysis instrument,has many characteristics such as testing multiple elements,being able to detect up to 70 elements,fast testing speed,and low detection limit.Mainly used in rare earth industry,silicon industry,petrochemical industry,ore analysis,metal smelting,geological research,drug safety,
experimental research,environmental testing and other fields.
Inductively Coupled Plasma Emission Spectrometer is a trace element composition analysis and testing instrument with high sensitivity photomultiplier tubes as detectors.It tests nearly 70 elements and has solid-state RF generator and automatic tuning matching technology;Equipped with a dedicated circulating cooling water system,argon gas conduit,cooling water pipe,and high sensitivity sampling system (high-efficiency atomizer with patented dual barrel atomization chamber).
