Introduction of Atomic Absorption Spectrophotometer
The AA2300 series atomic absorption spectrophotometer is the fifth
generation of atomic absorption spectrometers developed by wayeal.
The combination of a fully reflective dual beam beam splitting
system, a new lens coating process, an optimised fourth generation
Czerny-turner optical path design and an integrated optical
platform design delivers extremely high luminous flux while
providing excellent performance with low gain and high signal to
noise ratio, greatly improving sensitivity and stability.

Performance of Atomic Absorption Spectrophotometer AA2300
1. Any combination of flame, graphite furnace and hydride atomisers
2. Comprehensive flame safety interlocks to protect your
experiments
3. Advanced graphite furnace temperature control: highly sensitive
photosensitive elements and digital temperature control with high
temperature control accuracy
4. 8-lamp simultaneous preheating technology, which ensures the
stability of the lamp for the next measurement element and reduces
waiting times.

fast scanning, fast and accurate scanning of wavelengths.
6. Standard Furnace Chamber Camera: real-time monitoring of the
temperature ramping process inside the furnace chamber
Applications of Atomic Absorption Spectrophotometer
Atomic Absorption Spectrophotometer is now widely used in industry,
agriculture, biochemistry and pharmaceuticals, geology, metallurgy,
food inspection and environmental protection. The atomic absorption spectroscopy has become one of the most powerful means of metal element
analysis. And in many areas has been used as a standard analytical
method such as plant analysis in agriculture, fertilizer analysis,
feed analysis; biochemistry and pharmacology in the analysis of
body fluids, viscera and specimen analysis, drug analysis;
metallurgy in the analysis of iron and steel, alloy analysis:
geochemistry in the analysis of water quality, analysis of
atmospheric pollutants, soil analysis, rock mineral analysis; food
trace element analysis.
