Pharmaceuticals Trace Metal Analysis AA2250 AAS Atomic Absorption
Spectrophotometer
Product Introduction
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.

Product Features
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. 6 lamp holders preheat simultaneously to improve detection
efficiency
Product Application
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
