Wayeal AA23000 Flame Atomic Absorption Spectrophotometer AAS for
Metal Elements Analysis
Introduction of Atomic Absorption Spectrophotometer
Atomic absorption spectrometry (AAS) is an analytical technique that measures the concentrations of elements. Atomic absorption is so sensitive that it can measure down to parts per billion of a gram (µg dm–3) in a sample. The technique makes use of the wavelengths of light specifically absorbed by an element. They correspond to the energies needed to promote electrons from one energy level to another, higher, energy level.

Features of Atomic Absorption Spectrophotometer
1. An 8-lamp holder design alows for simultaneous illumination or
preheating to cater to a broader range of customer needs
2. Graphite furnace method automaticaly selects electronic dual-beam
3. One-click operation in the software alows automatic switching
between lamp positions; eight lamps can be illuminated or preheated
simultaneously, reducing warm-up time and increasing work
efficiency
4. Patented encoded lamp feature alows for automatic recognition of
element lamps through barcode scanning, which further raises the
level of automation in the instrument.
Application Industries of Atomic Absorption Spectrophotometer
Clinical Analysis: Analysing metals in biological fluids such as blood and urine.
Environmental Analysis: Monitoring our environment – eg finding out the levels of various elements in rivers, seawater, drinking water, air, petrol and drinks such as wine, beer and fruit drinks.
Pharmaceuticals: In some pharmaceutical manufacturing processes, minute quantities of a catalyst used in the process (usually a metal) are sometimes present in the final product. By using AAS the amount of catalyst present can be determined.
Industry: Many raw materials are examined and AAS is widely used to check that the major elements are present and that toxic impurities are lower than specified – eg in concrete, where calcium is a major constituent, the lead level should be low because it is toxic.
Mining: By using AAS the amount of metals such as gold in rocks can be determined to see whether it is worth mining the rocks to extract the gold.
