ICP-5000 is an ICP-OES developed product by Focused Photonics (Hangzhou), Inc. It is an achievement based on many years of extensive research and development of optical spectrum analyzing equipment. ICP-5000 has a rich spectral library with more than 50,000 optical spectrum lines available for selection and has a synchronous measuring ability to analyze 72 elements simultaneously. Via a new approach of industrial design, ICP-5000 also includes an optimized design of a two-dimensional spectroscopic system of middle ladder grating, an automatic fixed RF power supply, a custom-made anti overflow CCD and full-automatic spectrum acquisition system, an argon gas logic controller as well as a light chamber temperature control system. All in all, this makes ICP-5000 have properties of high resolution, large dynamic range, high stability and low limit of detection.
