AAS4M / AAS8A Atomic Absorption Spectrophotometer is a high-performance analytical instrument designed for quantitative determination of metallic elements in various sample matrices. The system measures the absorption of element-specific wavelengths by free atoms generated through flame atomization or graphite furnace techniques, providing accurate and reliable elemental analysis.
The AAS4M model features a 4-lamp manual configuration, while the AAS8A model offers an automatic 8-lamp turret with optional graphite furnace and autosampler compatibility. Built with a Czerny-Turner optical system and a closed optical bench design, the instrument ensures excellent wavelength stability, low baseline drift and high analytical sensitivity.
Equipped with automatic slit switching, high-speed self-reversal background correction and high-efficiency glass nebulizer, the system delivers precise results for research laboratories, quality control laboratories, academic institutions, pharmaceutical industries, metallurgy, food testing and environmental analysis applications.
The spectrophotometer supports multiple hollow cathode lamps and optional accessories including graphite furnace, autosampler, refrigerated circulating bath and oil-free air compressor, making it suitable for both routine and advanced elemental analysis.
