The TAS-986 is our company's highest-grade fully automatic atomic absorption spectrophotometer.

All operations are controlled through the PC, with the AA-Win software based on a WINDOWS platform.

The design of 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.
