Product description, Technical parameters and configuration

AAS8000, a newly-developed product of Atomic Absorption Spectrometer series, is an automatic graphite furnace atomic absorption spectrometer, used in micro-analysis, trace analysis and ultra-trace analysis of metallic element content and semi-metallic element content, above 60 measurable elements. AAS8000 applies the most advanced graphite furnace temperature control technology and it is fully automated, easy to operate, and quite reliable. AAS8000 is the first in the industry to use USB2.0 port, the latest electronic circuit system. AAS8000 realizes auto-control by computer (except for power switch).

Performance characteristics

Total-reflection achromatic optical system
Use concave lens instead of convex lens as focus, chromatic aberration caused by varied focuses of different elements is effectively solved and optical system efficiency is improved.

Full-automation design
Highly automated, all functions are monitored and controlled by computer (except for switch).

Integrated design
Integrated design of graphite furnace automatic sampler, graphite furnace power supply and atomic absorption spectrometer, decreasing electromagnetic interference of graphite furnace power supply, making assembly and disassembly of graphite furnace automatic sampler easier.

Responsive temperature control of graphite furnace, accurate warm-up temperature control
Large-power voltage transformer, micro-resistance cable, low-resistance graphite pipe and light-switch warm-up mode, calibrate the system according to software and hardware temperature curves; temperature control precision reaches ±1%.

Graphite furnace automatic sampler with 85 sample cups
Graphite furnace automatic sampler: highly precise polar coordinate positioning, stable operation, easy to use and highly-automated; if the automatic sampler isn’t configured, the software will choose manual sampling mode.

8 element lamps
Other 7 element lamps are preheated while one is working, time-saving and make element measurement much easier.

It is the first to use USB2.0 port instead of RS-232 port in the industry. Hot plug, compatible with computers without serial port, e.g. laptop.

More safety measures, making sample analysis more safe and reliable!
(1) Monitoring of cooling water pressure
(2) Monitoring of carrier gas pressure
(3) Monitoring of overheat of graphite furnace
(4) Temperature monitoring during graphite furnace chilling

Any errors detected during the above monitoring will set off the alarm and graphite furnace heating will be stopped; operation cannot be continued till the malfunction is solved.

Automatic carrier gas flow control
Use mass flow controller or integrated gas circuit to auto-control carrier gas flow.

Deuterium lamp background correction
When background signal is 1A, background correction ability is up to above 30 times; it can be upgraded to deuterium lamp plus auto-absorption background correction system.

Streamlined sheet metal external appearance

Proprietary intellectual property, powerful analytical software
User-friendly operating interface, automatic switch of Chinese and English software interface, automatic qualitative and quantitative analysis, auto-calculation of element content and auto-generation of test report.
