AAS - Atomic Absorption Spectrophotometer QualiAAS™ 3000F (Flame Furnace Type)

AAS – Atomic Absorption Spectrophotometer QualiAAS™ 3000F (Flame Furnace Type) is a high-precision analytical system designed for accurate metal analysis. It delivers strong selectivity, broad analytical applicability, high sensitivity, simple operation, cost-efficient performance, and reliable accuracy, making it suitable for demanding laboratory environments.

This instrument is widely applied in fields such as geology, mining, metallurgy, agriculture, forestry, hydrology, environmental monitoring, petrochemical processing, food and pharmaceutical safety, and third-party testing laboratories.

The flame system is built with high-stability flow control technology to ensure precise and automated gas regulation during operation. A durable gas-liquid separation unit, gas filtration system, and supporting components help maintain stable performance even in high humidity conditions or areas with limited gas supply.

Integrated safety interlocking mechanisms and intelligent alert functions provide automatic shutdown and alarm responses in case of operational irregularities, enhancing overall protection during use.

Its modular design and well-structured circuit architecture allow convenient maintenance, enabling fast component replacement and efficient servicing without complex procedures.

The system also supports expandable analytical techniques such as the hydride generation method, flame emission technique, and high-temperature flame analysis. Additional accessories, including an automatic flame sampler, further enhance workflow efficiency and analytical flexibility.
