Performance characteristics
Host
1. Total reflection achromatic optical system.
Using tyre mirror instead of convex lens as the optical focusing equipment of the instrument effectively solves the problem of different chromatic aberration of different elements' focal points and improves the efficiency of the optical system.
2. C-T monochromator.
A grating splitting system with 1800 lines/mm and 230nm blazing wavelength is adopted.
3. Eight-element lamp lighthouse.
Eight lamps are equipped with eight independent lamp power supplies, which work in Yi Deng and can be preheated by seven lamps, saving the time of changing lamps and preheating, and making element measurement faster and more convenient.
4. Fully automated design.
Except the main power switch, all functions of the instrument are monitored and controlled by computer.
5. USB2.0 communication mode.
The industry takes the lead in adopting USB2.0 communication interface, which improves the communication speed and is compatible with new computer systems.
6. Background correction system.
It has two background correction modes: deuterium lamp and self-absorption. When the background signal is 1A, the background deduction ability is more than 30 times.
7. The appearance adopts streamlined sheet metal process design, which is simple, fashionable and elegant
8. Analysis software with independent intellectual property rights, perfect functions and powerful performance.
Humanized operation interface, let your operation is easy, can switch between Chinese and English Windows style software interface, can run perfectly under Windows XP, Windows 7 and other operating systems, fully automatic qualitative and quantitative analysis, automatic calculation of element content, automatic generation of test report.
Flame system

2. Graphite furnace has high temperature control accuracy and fast temperature rise speed.
Using high-power transformer, micro-resistance cable and light-controlled temperature rise mode, and cooperating with software and hardware temperature correction system, the temperature control accuracy in high-temperature section can reach 1%.
3. More safety protection measures make sample analysis safer and more reliable.
1) Cooling water flow monitoring
2) Carrier gas pressure monitoring
3) Graphite tube temperature monitoring
4) Graphite furnace temperature monitoring
4. Automatic carrier gas flow control.
The internal gas and external gas of graphite furnace are automatically controlled by computer according to the software heating process.
Automatic sampler
150-bit universal automatic sampler for rotary disc flame graphite furnace.
Polar coordinate rotary disc automatic sampler has high positioning accuracy, stable and reliable operation and convenient use and maintenance. (AAS8000-M and AAS9000-M products are in manual injection mode without automatic injector)
