Flame Atomic Absorption Spectrophotometer

Product Detailed

Flame Atomic Absorption Spectrophotometer Innovated rich oxygen air-acetylene flame analysis technique(WFX-110B)

Flame Atomic Absorption Spectrophotometer

Features

1 Innovated rich oxygen air-acetylene flame analysis technique(WFX-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°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 break-through in flame AAS analysis

2 Flame atomization system with flame emission burner

2.1 A flame emission burner head can be installed to perform flame emission analysis to Alkali metals as K, Na etc.(WFX-110B/120B)

3 Accurate fully automated control system

3.1 Automatic multi-lamp turret, automatic adjustment of lamp current and optimization of light beam position

3.2 Automatic wavelength scanning and peak picking

3.3 Automatic spectral bandwidth changing

3.4 Automatic ignition

4 Perfect safety protection measures

4.1 Alarm and automatic protection to fuel gas leakage, abnormal flow, insufficient air pressure and abnormal flame extinction in flame system

5 Advance and reliable electronic design

5.1 Adopting large-scale programmable logic array and Inter I2C bus technology

5.2 European type sockets and AMP adapters with high reliability to ensure long term reliability of the whole electronic system

6 Easy and practical analysis software

6.1 Easy-to-use AAS analysis software is made under Windows operating system, realizing fast parameter setting and optimization

6.2 Automatic sample dilution, automatic calculation and analytical result automatic print out
