AAS-110A/120A/130A, Flame/Graphite Furnace Atomic Absorption Spectrophotometer
Features:
Innovated rich oxygen air-acetylene flame analysis
technique (AAS-110A)
The patented flame analysis technique adopting
rich oxygen air-acetylene flame as the substitution
for nitrous oxide-acetylene flame for high
temperature element analyses, such as Ca, AI, Ba,
W, Mo, Ti, V, etc. Flame temperature is continuously
adjustable between 2300-2950°C, which makes it
possible to choose the best atomization temperature
for different elements. It features easy operation, low
analysis cost and wide flame AAS analytical range.
Rich oxygen flame will not pollute the environment
and is not harmful to human bodies. It’s a
break-through in flame AAS analysis.
Integrated flame/graphite furnace atomization
system, changeable with flame emission burner
●
Automatically controlled changeover of the
integrated flame and graphite furnace atomizer
featuring easy operation and time saving
eliminates human labor.
●
A flame emission burner head can be installed to
perform flame emission analysis to Alkali metals as
K, Na etc. (AAS-110N120A)
