Description

IFX-110B/120B/130B

Flame/Graphite Furnace Atomic Absorption Spectrophotometer

Features :

Innovated rich oxygen air-acetylene flame analysis technique (IFX-110B)
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 temeperature is continuously adjustable between 2300-2950 Celsius, 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 break-through in flame AAS analysis

Flame atomization system with flame emission burner
A flame emission burner head can be installed to perform flame emission analysis to Alkali metals as K, Na etc. (IFX-110B/120B)
