PC software control: can flexibly select the flame and graphite furnace atomizer (optional). All parameters of the instrument are set by computer software, and the program is automatically controlled.
Three working modes can be selected: absorbance (continuous integration signal, peak height/peak area integration signal), concentration straightness, and flame emission intensity. It has four signal modes: atomic absorption, background absorption, background deduction correction, and emission intensity.
Integrated floated optical platform design can obviously improve the optical system shock resistance and keep stable though use the optical signal for a long term.
Eight light stands can be changed automatically, with the functions of simultaneous preheating, automatic rotation switching, automatic ignition, and automatic optimization of the working conditions of hollow cathode lamps.
Position adjustment: The ideal height and front and rear position of the flame burner are automatically set.
Perfect safety interlock protection device: The system has an alarm safety protection function for incorrect connection of combustion head, gas leakage, air under pressure, abnormal flameout, etc.
Complete safety chains protection equipment: the function of warning and automatic safety protection towards the wrong burner, leakage of the gas, under voltage of air, and the abnormal flameout.
Deuterium lamp and self-absorption background regulation. It has the functions of automatic wavelength scanning, automatic gain, background correction, automatic energy balance, and automatic peak search according to the peak search method.
Data processing: super strong database, possesses more than 500 data self-storage and cut-off storage function, can store the analyzed result with the form of EXCEL and the testing method and the result can be randomly called.
Measuring method: flame absorption method and emission method.
Result printing: parameter printing, data result in printing, and diagram printing.
