Description
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 flameout.
* 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 format.
