Principle
Atomic absorption spectrophotometer works based on atomic absorption spectroscopy (AAS). The sample to be tested is converted into a ground state atomic vapor in an atomization system such as a flame or a graphite furnace. When light from a specific wavelength light source (such as a high-performance element lamp) passes through the atomic vapor, the ground state atoms in the vapor selectively absorb light of its characteristic wavelength, resulting in a decrease in light intensity. By measuring the degree of weakening of light intensity and comparing it with a standard Linear dispersion, the amount of specific elements in the sample can be quantitatively analyzed. The instrument uses a full-band deuterium lamp and self-absorption technology for Background correction to eliminate interference from non-characteristic absorption.
Applications
Environment monitoring, food safety, drug inspection, geology and minerals, metallurgy and chemical industry, clinical medicine, scientific research and education

Notice
• Please read the instrument instruction manual carefully before operation and receive relevant training.
• Ensure that the gas path is connected correctly and sealed well, and pay attention to safety when using the intelligent gas control module.
• When using high-performance element lamps, do not touch the glass surface of the lamp tube.
• Light spectrum Bandwidth and Background correction mode are correctly selected according to sample properties and analysis requirements.
• Atomizer (especially graphite furnace) heating procedures need to be set reasonably to avoid damage.
• Regular instrument maintenance and calibrating to ensure the accuracy of analytical results.
When handling samples, comply with relevant laboratory safety regulations, especially when handling toxic or corrosive samples.
• Software operations should be carried out under an authorized MS Windows system.
