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.
