Atomic Absorption Spectrophotometer

About Atomic Absorption Spectrophotometer

Features:

Innovated rich oxygen air-acetylene flame analysis technique:

 

The patented flame analysis technique adopting rich oxygen air-acetylene flame as the   substitution for nitrous oxide-acetylene flame for high temperate element analysis, such as Ca, Al, Ba, W, Mo, Ti, V etc. Flame Temperature is continuously adjustable between 2300-2950 ºC, which makes it possible to choose the best atomization temperature for different elements. It features easy operation, low analysis cost and wide flame AAS analytical range. Rich oxygen flame will not pollute the environment and is not harmful to human bodies. It’s a break through in flame AAS analysis.

 

Integrated flame/graphite furnace atomization system, changeable with flame emission burner:

 

• Automatically controlled changeover of the Integrated flame and graphite furnace automizer featuring easy operation and time saving eliminated human labor.
• A flame emission burner head can be installed to perform flame emission analysis to Alkali metals as K, Na etc.

 

Accurate fully Automated Control System:

• Automatic 6 lamp turret, automatic adjustment of lamp current and optimization of light beam position.
• Automatic wavelength scanning and peak picking.
• Automatic special spectral bandwidth changing.
• Automatic changeover between flame and graphite furnace operation, automatic optimization of position parameters automatic ignition and automatic gas flow setting.

Advanced User-Friendly Operation

With a digital LCD display and Windows-based analytical software, the AAS-4 provides intuitive controls and swift data interpretation. The single, double, or four burner capacity positions this instrument as a versatile choice for diverse elemental analysis tasks in modern laboratories. The integrated printer and RS232 interface facilitate seamless data recording and transfer.


Superior Analytical Performance

Achieve exceptional resolution-better than 0.2 nm-across a broad wavelength range of 190 to 900 nm. With a baseline stability under 0.004 Abs/30 min and accuracy better than 0.5%, every analysis remains dependable. Features like adjustable lamp current and automatic fuel control further support precision and reproducibility.


Built-in Safety and Reliability

Operational safety is ensured with automatic fuel cutoff, burner lift-off detection, and a safety interlock system. The AAS-4's corrosion-resistant stainless steel housing not only ensures longevity but also provides additional protection in harsh laboratory environments. The auto-ignition and adjustable flame options support both convenience and operator protection.
