Wayeal 220V Graphite Furnace AAS Laboratory Atomic Absorption
Spectroscopy Machine in Lithium Ore Analysis
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
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.
Gemstones are also graded on the basis of the presence of certain trace metals. Elemental composition of archaeological artefacts is helpful for tracing their source.
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
