TAS-990AFG/TAS-990G atomic absorption spectrophotometer

Instrument Introduction:

As a professional analytical instrument manufacturing enterprise, Beijing Puxi General Instrument Co., Ltd. has long been committed to the research and development of atomic absorption spectrophotometers.
In 1996, the Zhongguodiyi fully automatic transverse heating graphite furnace atomic absorption spectrophotometer was launched, which was well received by users for its good performance and reliable quality. It won the gold medal at the BCEIA exhibition in 1997.
For users with higher analytical needs, the AAS and TAS-990 series atomic absorption spectrophotometers, as the new generation of iconic products, have reached a higher level of instrument performance, providing more reliable guarantees for element quantitative analysis.

To meet the needs of different application fields, the instrument has different configurations and functions: F represents flame type, G represents graphite furnace type, A represents automatic type
