Persee AA990F *NEW* Atomic Absorption Spectrophotometer

Cambridge Scientific ID #: 21352

Features:

 

The AA900 Atomic Absorption Spectrometer is a versatile entry level instrument with a computer controlled Air/Acetylene flame for general laboratory requirements. Due to its high sensitivity and excellent performance the instrument can be used for a wide range of applications. The versatile instrument is available in three configurations:

AA990F-Flame atomizer only.

AA990G-Graphite furnace atomizer only. 

AA990FG-Combined with flame and graphite furnace atomizer switch aromatically. 

Common Applications include: Agricultural, Environmental, Petrochemical, Clinical.

â—† Easy-to-use automation software 

â—† Integrated safety precautions for user protection

â—† Precision accuracy with integrated correction system 

â—† Life cycle value, best choice for less than 8 elements of analysis
