GA-9916 Atomic Absorption Spectrometer
Instrument description
GA-9916 Flame graphite furnace integrated atomic absorption spectrometer is a fully automatic intelligent flame graphite furnace integrated atomic absorption instrument developed by the company with many years of research and development experience, used to determine the amount of major, trace, trace metal elements and semi-metallic elements in various substances. The machine adopts PC and Chinese interface operating software, making the instrument easy to operate, intuitive and easy to understand. By using advanced electronic circuit system and USB3.0 communication control, the automatic adjustment of wavelength scanning, peak searching, spectral passband width, rotating element lamp frame, atomizer height and position, gas flow, lamp current and photomultiplier negative high voltage is realized. The instrument stores reference conditions for analysis of all the measured elements of a variety of analytical methods, and users can modify the operating conditions according to needs, and can save the operating conditions and working curves and test results, which can be used and processed again.

Performance characteristics
- Integrated design
Using series optical path design, the position of flame graphite furnace atomizer is fixed, the software automatically switches, without hardware replacement, one-second switching, avoiding the error caused by mechanical switching, improving the stability and maintainability of the instrument.
- C-T monochromator
The optical splitting system with 1800 lines /mm and 230nm flash wavelength is adopted.
- Eight element light beacon
One lamp work, up to seven lamps can be preheated, saving the lamp change and preheating time, making the element measurement faster and more convenient.
- USB3.0 communication mode
The industry takes the lead in adopting 3.0 communication interface, which improves communication speed and is compatible with the latest computer Windows 10 system.
- Independent intellectual property rights
With relevant patent certificates and software copyright certificates, user-friendly operation interface, so that your operation is easy, you can switch Chinese and English Windows style
Software interface, can run perfectly under Windows 7, les fenêtres 10 and other operating systems, automatic qualitative and quantitative analysis, automatic calculation of element content, automatic generate test reports.
- Background correction system
Element lamp and deuterium lamp double switching and background deduction, with deuterium lamp and self-absorption two background correction modes, background signal 1A, buckle the background capacity more than 60 fois.
- Fully automated design
In addition to the host power switch, all the functions of the instrument are monitored and controlled by the computer, and the software automatically determines the best test conditions for each element.
- Total reflection achromatic optical system
Using concave mirror instead of convex lens as the optical focusing device of the instrument, the color difference problem of different elements is effectively solved, and the efficiency of the optical system is improved.
