Pharmaceuticals Trace Metal Analysis AA2300 AAS Atomic Absorption Spectrophotometer
Introduction of Atomic Absorption Spectrophotometer
Atomic absorption spectroscopy or AAS, is a technique for measuring the concentrations of metallic elements in different materials. As an analytical technique, it uses electromagnetic wavelengths, coming from a light source. Distinct elements will absorb these wavelengths differently. It gives a picture of what concentrations of a specific element there is in whatever material, or liquid, is being tested.

Features of Atomic Absorption Spectrophotometer
1.Upon switching modes, the system automaticaly adjusts to the optimal positioning for graphite furnace and fame modes
2. The ame atomizer and graphite furnace atomizer are congured in parallel, significantly shortening the light path and resulting in minimal loss of optical energy, thus achieving high sensitivity
3. Real-time monitoring of air pressure
4. Real-time monitoring of acetylene pressure (high/low pressure)
5. Real-time monitoring of water seal levels (high/low water level)
Applications of Atomic Absorption Spectrophotometer
Foods and Beverages – In synthetic processed foods, metal pickup takes place due to contact with processing equipment and catalytic conversions. Consumer awareness on food safety is increasing by the day so manufacturers have to ensure that the trace metals do not exceed the permissible limits and this requires rigorous quality control through atomic absorption spectroscopy and other sophisticated instruments.
Oil and Petroleum – Both edible oils and mineral oils require refining before consumption. Such refining operation can involve distillation as well as catalytic refining. Uptake of metals during such operations can lead to deterioration of performance or consumer hazards. Trace metal analysis of engine oil provides useful diagnostic information on the wear and tear of engine parts.
Agriculture – Trace metal constitution of soils in addition to their acidic or basic nature is essential to establish their productivity and nutrient value. Trace metal composition of plants (leaves, stems and roots) gives a fair idea on how the uptake of minerals gets distributed under different growth conditions
