220V Flame Graphite Furnace Metal Analysis Atomic Absorption
Spectrometer AAS
Introduction of Atomic Absorption Spectrophotometer
Atomic Absorption Spectroscopy is an instrumental analysis
technique for rapid trace metal analysis.It is based on element
specific wavelength light absorption by ground state atoms in the
flame or electrothermal graphite furnace.It finds immense applications in the analysis for trace metals in
soils, lakes, rivers, oceans, and drinking water, pharmaceuticals,
foods and beverages, geological and mineralogical samples,
petroleum products, biological fluids and specimens and forensic
analysis.

Features of Atomic Absorption Spectrophotometer AA2300
1. Stability: Double-beam system can automatically compensate the
light source drift and wavelength drift caused by the variation of
temperature (with the function of the eliminating the affection of
wavelength drift on the base line stability) and electronic circuit
drift so as to reach a good basic line stability.
2. Full-reflection dual-beam optical path, high optical path
stability
3. High precision of measurement: Gas path system is equipped with
precision pressure stabilizing and current stabilizing devices to
reach stable flame and low noise. Specially designed fine light
beam passes through the flame to ensure a high precision analytical
test and low characteristic concentration.
4. 8 lamp holders preheat simultaneously to improve detection
efficiency
Applications of Atomic Absorption Spectrophotometer
Mining and Geology – The elemental composition of minerals and rocks provide valuable
information on the commercial feasibility of conducting mining
activities in areas explored. After mining, the ores and minerals need to be tested for composition for the
efficiency of refining operations.
Environmental Monitoring – Environmental monitoring for trace metal contamination of
industrial effluents, oceans, rivers and lakes is important for
establishing the safety of water for drinking and commercial use. It is important to
establish if such samples are within the safety limits set by
regulatory bodies.
Materials Development – Common properties of materials such as hardness, brittleness,
grain size, crystallinity and amorphous nature are significantly influenced by composition
and trace metals. Trace metal analysis can provide useful
information on the performance properties of such materials.
