Introduction:

1. Optical suspension system. Superb by design, the instrument stands up to the test of shaking environment and tough temperature condition.

2. Uniquely designed, one system can be configured to have both flame and graphite furnace installed. The switching between these 2 takes about a few seconds. AA-7000 is the most compact AAS system in the world.

3. Titanium atomized system. It takes advantage of the aero-space technology, use titanium
   atomized system and burner. It is more resist to erosion, oxidation, and high temperature. The design helps increasing the lifetime of the instrument.

4. 1800 lines/mm diffraction grating, to achieve higher resolution and higher energy.

5. Deuterium-lamp and background deduction technology, to make the result adjusted more accurately.

6. Alarming system, in order to guarantee the safety of lamps, graphite furnace, and flame, special design was considered at the beginning. so to make an instrument more reliable and safe to use.

7. Option to our HG-01 hydride generator, to help your analysis on these elements as AS, Pb, Se, Hg etc..

8. Graphite furnace auto sampler, auto sampler the process of preparation of standard solvents and sample. Repeatability is better than 98%.
