UFX-210 Atomic Absorption spectrophotometer(AAS)
FEATURES:
Innovated Rich oxygen air-acetylene flame analysis technique
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, Al, Ba, W, Mo, Ti, V, etc. Flame temperature is continuously adjustable between 2300-2950℃, 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 is 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
Accurate fully automated control system
Reliable fully automatic graphite furnace analysis
Perfect safety protection measures
Advanced and reliable electronic design
Easy and practical analysis software
