Main features:

Fully controlled by PC, with flexible options for flame and graphite furnace atomizers. The lamp current, negative high voltage, working wavelength, and combustion conditions of the instrument are all input by a highly automated atomic absorption spectrophotometer through a PC menu.

Provide three reading methods for measuring absorbance, concentration, and emission intensity: continuous, peak height, and peak area. It has four signal methods: atomic absorption, background absorption, background correction, and emission intensity.

The integrated suspended optical platform design significantly improves the seismic resistance of the optical path system, ensuring stable optical signals even after long-term use.

8 lamp stands with functions of simultaneous preheating, automatic rotation switching, automatic ignition, and automatic optimization of the working conditions of hollow cathode lamps.

It has functions such as fully automatic wavelength scanning, automatic gain, background correction, automatic energy balance, and automatic peak searching by peak retrieval method.

● Comprehensive safety interlock protection device: The system has alarm safety protection functions for incorrect connection of the combustion head, gas leakage, air under pressure, abnormal shutdown, etc.

The concentration calibration of 1-9 point standards can be performed with a single standard sample for slope adjustment. It has functions such as linear regression, curve fitting, linear and nonlinear standard addition method, baseline compensation, mean and relative standard deviation.

Data processing: A super powerful database with self storage and power-off storage functions for up to 500 data points. The analysis results are saved in the form of Excel spreadsheets, and the testing methods and results can be called at any time.

Optional communication module with soil testing formula fertilization dedicated software that meets the communication requirements of the Soil Testing Standard (FERTREC).

● Position adjustment: The optimal height and front and rear positions of the flame burner are automatically set

● Testing methods: flame absorption method, flame emission method

● Result printing: All readings, measurement results, calibration curves, and operating conditions.
