Product Detail

ATOMIC ABSORPTION SPECTROPHOTOMETER DW-220A B

Higher Reliability

More than 40 years of experience in AAS R&D and manufacturing
Aberration eliminated C-T type monochromator with stable performance
Modular electronic circuits are designed for easy operation and maintenance 
Reliable gas-liquid separators and fuel gas filter devices provide robustness even in high humid and harsh environments. 

Higher Safety

Intelligent feedback detection technique, real-time monitors the lamp current and protects the hollow cathode lamps.
Simple structure modular gas supply system provides a lower fault rate, higher safety, and reliability.
High-precision mass flow controllers and stable electronics in the flame systems control the fuel flow accurately. The temperature control protection system together with dual air circuit breakers in GF system, effectively prevents current overload or abnormal temperature rise.  
Multiple safety interlock devices and prompt information displays prevent possible dangers.

Easier to use

Unique light source system， with 8-lamp turret fully automatic change and optimization， supports 1 lamp working and 7 lamps preheating at the same time. 
Easy changing emission burner for easily ionized elements such as K, Na, etc., with linear range 3 times that of normal flame.
Temperature control modes in graphite furnace analysis can be switched over easily between optical control and constant voltage control, according to different elements and graphite tubes, for the best results and to extend the lifetime of graphite tubes. 
One-click automatic optimization, easy analytical condition setting, and expert database support, for easy operation with no worries.

Fewer Faults

Hamamatsu’s high-performance PMT as the detector.
Molding PPS spray chamber has high chemical stability, withstanding high temperature and strong acids, etc..  
The communication system is based on the mature bussing technique. It improves anti-jamming capability and data transmission reliability.
