Features

  • Completely controlled by PC, can flexibly select the flame and graphite furnace atomizer (optional).
  • Integrated floated optical platform design improves the optical system shock resistance stable.
  • Eight light stands can be changed automatically and preheat the eight lights meantime as well as optimize the working condition of the hollow cathode lamp.
  • Position adjusting: the flame burner can be set on the best position automatically.
  • Fully automated wavelength scanning and peak searching.
  • Complete safety chains protection equipment: warning and automatic safety protection for the wrong burner connection, leakage of the gas, under voltage of air and the abnormal flame out.
  • Deuterium lamp and self-absorption background calibration.
  • Measuring method: flame absorption method and emission method.
  • Result printing: parameter, data result and diagram.
  • Data processing: more than 500 data self-storage and cut-off storage, the analyzed result is stored in EXCEL forma
