AA2300 Pneumatic Graphite Furnace Atomic Absorption
Spectrophotometer AAS
Introduction of Atomic Absorption Spectrophotometer
Atomic Absorption Spectrophotometry (AAS) is used to determine the
concentrations of individual elements in a sample by measuring the
selective absorption of light by gaseous atoms produced by spraying
a solution into a flame (FAAS) or by evaporation in a carbon tube
(CFAAS). AAS is commonly used for trace metal analysis of a wide
range of sample types in the environmental sciences, food and
beverage, chemical and pharmaceutical sectors for impurity or
contamination monitoring and quality control, as well as the rapid
assessment of raw materials. It is also used in a clinical setting
for the analysis of biological fluids, such as blood and urine.

Features of Atomic Absorption Spectrophotometer
An 8-lamp holder design alows for simultaneous i lumination or
preheating to cater to a broader range of customer needs.
Newly developed software modules offer a user-friendly interface
with high automation, ensuring improved human-computer interaction.
A Graphite Furnace Visualization System enhances convenience in
conguring the autosampler while concurrently monitoring variations
in each temperature stage of the sample.
A suspended, modular autosampler permits effortless 3-second
removal or instalation; its 100+8 position design meets the demands
of large-volume sample testing.
Pneumatic graphite furnace control facilitates easy graphite tube
replacement, and the hermetic furnace chamber design boosts
detection sensitivity.
A wider linear dynamic range caters to diverse analytical
requirements across different industries.
Optimized graphite furnace temperature control algorithms guarantee
repeatability in testing high-temperature elements (such as Al, Mo,
V, Ti, etc.)
Supports congurations for single ame, single graphite furnace, and
a combined ame-graphite furnace system.
