TAS-986 Atomic Absorption Spectrometer (Flame & Furnace)
$24,800

The TAS-986 is one of the highest-grade fully automatic atomic absorption spectrometers. All operations are controlled through the PC, with the AA-Win software based on a WINDOWS platform. The design with the flame burner and graphite furnace in one compact unit enables automatic interchanging of two analytical methods.

There are two background correction methods, self-reversal background correction and deuterium lamp background correction, to ensure the most precise analytical results. A self- aligning eight-lamp turret makes for user-friendly multi-elemental atomic measurements. The unique furnace heating design ensures uniform heating and guarantees measurement accuracy. All around automatic safety precautions ensure reliable operations. ONE (1) YEAR WARRANTY included.

Please allow up to four (4) weeks for delivery.

Automatic adjustment of burner height for optimized analysis conditions. Automatic Reflecting/Transmitting beamsplitter positioning (to lead the light of deuterium lamp into optical path) when the Deuterium Lamp Background Correction function is selected. Automated wavelength scanning and peak-seeking Automatic switchover of spectral bandwidth (5 choices). Automatic negative voltage and lamp current adjustment, automatic AA and BG energy balance, automatic igniting and interlock protection in case of flameout.

Safety Assurance

Flame Monitoring: Constant monitoring. When accidental flameout occurs, an alarm is given and the acetylene flow is stopped immediately Pressure Monitoring: Constant air pressure detection. When abnormalities are detected, acetylene flow will be automatically cut off for safety fire extinguishing. The argon gas pressure monitor will disconnect the electricity to the graphite tube when an absence of the protective argon gas is detected. Cooling water flow monitoring: The power supply to the furnace will only be activated for heating when the cooling water flow is determined enough to cool down the furnace body. Graphite Tube Fracture Protection: Power supply used for heating is automatically shut off and an alarm is given if a sudden graphite tube fracture is detected.
