Atomic Absorption Spectrophotometer (AAS) Merk Innotech AAS_02_(IFX-110A)

Description

IFX-110A/120A/130A
Flame/Graphite Furnace Atomic Absorption Spectrophotometer

Features:
Innovated rich oxygen air-acetylene flame analysis technique (IFX-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, Al, Ba, W, Mo, Ti, V, etc. Flame temeperature is continuously adjustable between 2300-2950?, with 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

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 akali metais as K, Na etc.(IFX-110A/120A)

Accurate fully automated control system
