Product description, technical parameters and configuration


ICP-6800 Inductively Coupled Plasma Optical Emission Spectrometer(standard)

Application Field

Inductively coupled plasma emission spectrometer(ICP6800) developed by Macylab Instruments with many years of technology accumulation. It is used to measure traces and traces of various substances (dissolvable in hydrochloric acid, nitric acid, hydrofluoric acid, etc.),and the content of metal elements or non-metallic elements. It is stable and reliable and with high degree of automation and easy operation.

At present, instruments are widely applied in various fields such as rare earth, geology, metallurgy, chemical industry, environmental protection, clinical medicine, petroleum products, semiconductor, food, biological samples, criminal science, agricultural research and so on.
