The AA-7000 series’ newly developed 3-D optical system is capable of producing maximum performance for both flame and furnace detection. This is achieved through optimal adjustment of the light beam and digital filter, and by using optical components that restrict light loss.
Advances in optics and a new graphite furnace design achieve improved lower limits of detection for furnace analysis (comparison with previous Shimadzu models). This superb analysis performance is possible in all fields.
The optimal background correction methods, high-speed self-reversal method (SR method) and deuterium lamp method (D2 method), are installed as standard.
Safety is an extremely important consideration for flame atomic absorption spectrophotometers using acetylene gas. The AA-7000 Series instruments are the first* ones in the world fitted with a vibration sensor as standard. They also incorporate a comprehensive range of safety mechanisms, including gas leak detectors. Shimadzu in-house investigation. Current as of November 2008.
When attached to the AA-7000F, the optional AAC-7000 Auto Atomizer Changer* creates an integral burner and furnace that remains permanently installed in the combustion chamber. It supports both flame analysis of high-concentration samples and furnace analysis of trace samples, without changing the atomizer unit. The integral construction with the atomizer saves space. The AAC-7000 cannot be attached to an AA-7000G instrument. The AA-7000 Series can be upgraded by adding units to allow the system to handle the analysis targets.
The AA-7000 series gives users a single high-performance autosampler for both flame and furnace, saving capital cost and set-up time.
