Product Description

DW-AA4730FG Atomic Absorption Spectrophotometer
Flame-Graphite Furnace Automatic Integrated

Features

1. Permanently equipped with both flame and graphite furnace atomize, switched by computer. Automatically determine the best position.Vertical 8 light stand, rotating light search by computer control, preheating and optimizing use conditions.
2. Total reflection optical system, using two aspherical optical elements to strictly correct astigmatism, effectively improve the monochromator entrance slit energy.Automatic wavelength scanning and peaking.
3. With self-absorption correction and deute riu m lamp correction 2 background deduction methods. when the background signal 1A, deuteri um lamp background correction capability >60 times.
4. Automatically cut off the gas when the gas pressure is insufficient, the power supply is interrupted. the flame is turned off or the combustion head is not matched, to ensure safety.Equipped with HD camera, the automatic graphite furnace injection needle position adjustment is more convenient, the whole process of graphite furnace injection visualization.
5. Equipped with waste liquid level sensor to ensure data stability and safe use.
6. Software Functions
7. Method save and call: Different experimental methods and parameter Settings can be saved. This makes the method switching more convenient during the analytical test, and can also improve the consistency and repeatability of the analytical test.
8. Concentration calculation: standard curve method and standard addition method are provided. Standard curve method can choose single point calibration or multi-point calibration, multi-point calibration can choose 1,2, 3 functions and mutual conversion, support up to 30 concentration points repeated 20 times of standard sample calibration, automatic calculation of average value, standard deviation (SD) and relative standard deviation (RSD).
9. Sample information table editing and data processing functions: provide weight factor, volume factor, dilution factor and other sample information editing, can calculate the solid sample concentration (sample content) directly, improve the integrity of the experiment report.
10. Data export and report generation: software supports data export capabilities, which can be processed into excel formats, which facilitate statistics and further analysis. At the same time, the software also provides the reporting generation function.which allows users to generate complete experimental reports as required, and the storage and printing is used for recording and filing.
