Atomic Absorption Spectrophotometer FM-AAS-A201 Catalog

Description :

Atomic Absorption Spectrophotometer FM-AAS-A201 is a flame type automatic PC controlled analyzer. Unit is assembled with 4-lamp turret, air-acetylene flame, D2 background correction, software and Cu, Mn, Hg hollow cathode lamps. Adopted with rich oxygen air-acetylene flame analysis technique as substitution to nitrous oxide-acetylene flame for high temperature element analysis such as Ca, Al, Ba, W, Mo, Ti, V, etc. Flame temperature is continuously adjustable between 2300 to 2950°C, enables it to select best atomization temperature for different elements. Features easy operation, low cost analysis and wide flame AAS analytical range. Its Rich oxygen flame is environmental nonpolluting and harmless to human bodies.
