Wayeal 220V Graphite Furnace AAS Laboratory Atomic Absorption
Spectroscopy Machine in Lithium Ore Analysis
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.

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. Similarly, trace metal analysis
is of great value in prospecting for oil and water deposits.
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. Environmental monitoring also plays a
significant role in the evaluation and feasibility of the site for setting up commercial projects.
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.
Pharmaceuticals – Trace metal analysis plays an important role in formulation
development, catalyst efficiency and dosage limits. Most elements
have a beneficial role up to certain prescribed limits but beyond such limits the
effects are harmful.
