Drawell brand highquality atomic absorption graphite furnace spectroscopy

DW-AAS-110A/120A/130A

Flame/Graphite Furnace Atomic Absorption Spectrophotometer

FEATURES:

Innovated Rich oxygen air-acetylene flame analysis technique (DW-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, 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

·           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. (DW-AAS-110A/120A)

Accurate fully automated control system

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

·         Automatic wavelength scanning and peak picking

·         Automatic spectral bandwidth changing

·         Automatic changeover between flame and graphite furnace operation,  automatic optimization of position parameters, and automatic ignition

Reliable fully automatic graphite furnace analysis

·         Adopting FUZZY-PID and dual curve mode light-controlled temperature control technique, temperature auto-correction technique, ensures fast heating, good temperature reproducibility and high analytical sensitivity.  The temperature control accuracy is less than 1%.

·         Graphite furnace with pneumatic control and pressure lock ensures constant pressure and reliable contact.

Perfect safety protection measures

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

·         Alarm and protection function to insufficient carrier gas and protective gas pressure, insufficient cooling water supply and over-heating in graphite furnace system.

Advanced and reliable electronic design

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

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

Easy and practical analysis software

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

·         Automatic display of measured data, automatic calculation and analytical result automatic print out.
