Atomic Absorption Spectrophotometer Product Information

Product Evaluation

Analysis of Plastic Samples Using an AA Spectrophotometer
Atomic absorption spectrophotometers are used to analyze trace hazardous inorganic elements in plastic, in particular cadmium,
lead, and arsenic. If there are only a few target elements being measured, this allows measuring them efficiently at low cost. Plastic Materials Evaluation of
Plastic samples are normally pretreated by adding acid to thermally decompose them before measuring. Some plastics can
be simply dissolved in an organic solvent before measurement. If target elements are present in higher concentrations, flame
atomization is used, which allows a shorter measurement time. However, when measuring trace quantities, selecting the furnace
measurement method allows analyzing the samples more efficiently.

Features of AA-7000

• System configurations advancing together with needs Raw Materials Evaluation of
Compact dedicated flame models can be converted to a dual atomizer system
that can automatically switch between flame/furnace modes. Dedicated furnace
models are also available.
• Fully featured flame analysis
A newly developed 3-dimensional double-beam optical system and sturdy
hardware provide outstanding stability.
• Advance safety technology AA-7000 Dual Atomizer System Product Evaluation
The system features many safety mechanisms, such as the world's first automatic
flame extinction via flame vibration sensor, multimode automatic gas leak check,
and use of flame resistant materials.
• World-class high-sensitivity furnace
Lower limit of detection performance was improved by reducing noise with
state-of-the-art optics. Stability is also improved by digital temperature control
and digital gas control.
• Dual atomizer system Product Information
(automatic flame/furnace mode switching function)
Automatically switches the atomization unit by software operation. A newly
developed drive mechanism cuts the switchover time in half from the previous model.
• Multifunctional autosampler
A single autosampler supports both flame and furnace analysis.
Commercial pipette tips can be used for nozzles in the furnace mode. WizAArd High Functionality Software
A rinse port in the overflow mechanism ensures nozzles are rinsed properly.

• Features easy to understand and use WizAArd software
Extensive display features and highly flexible settings
Supports system control and precision control and includes hardware validation
software.
