WFX-210 Atomic Absorption Spectrophotometer

Features for WFX-210 Atomic Absorption Spectrophotometer

 

Innovated flame analysis technique

  • The patented flame analysis technique adopting oxygen-rich air-acetylene flame as the substitution for nitrous oxide-acetylene flame for high temperature element analyses, such as Ca, Al, W, Mo, Ti, V, etc. Flame temperature is continuously adjustable between 2300-2950ºC, which makes it possible to choose the best atomization temperature for different elements. It features easy operation, low analysis cost. Oxygen-rich flame will not pollute the environment and is not harmful to human bodies. It is a break-through in flame AAS analysis.
  • Popular Czerny-Turner grating monochromator with 1800l/mm provides higher resolution.
  • All plastic pre-mix spray chambers with high anti-corrosion ability.

 

Accurate and reliable graphite furnace analysis

  • Light-controlled graphite furnace power supplier, adopting FUZZY-PID temperature control technique and dual curve working mode, ensures fast heating, accurate and stable temperature control and good temperature reproducibility. Temperature auto-correction function provided.
  • Graphite furnace with pneumatic control and pressure lock ensures constant pressure and reliable contact.
  • High accuracy and reproducibility of the graphite furnace auto-sampler, realizing fully automation of graphite furnace analysis.

 

Fully automated control system

  • Auto-changeover and position optimization of integrated flame/graphite furnace atomizer.
  • Automatic 6-lamp turret. High performance HCL can be used directly, which features high intensity spectral line and low background.
  • Auto-ignition, automatic spectral bandwidth selection.
  • Fully automated wavelength scanning and peaking.
  • Adopting mass flowmeter with program control ensures accurate gas intake volume.
  • Automatic setting of Gas flow

 

Perfect safety protection measures

  • Alarm and automatic safety protection to fuel gas leakage, air pressure deficiency and abnormal flame extinction
  • Spray chamber made of explosion-proof material, all titanium burner and explosion-proof stopper for flame analyses.
  • Alarm and protection function to argon pressure deficiency, insufficient cooling water supply, over-heating and over-current ect. In graphite furnace analyses.

 

Advanced and reliable electronic design

  • Adopting large-scale programmable logic array and Inter IC bus technique and highly reliable adapters for electric design.
  • European type sockets and AMP adapters with high reliability to ensure long term reliability of the whole electric system.
  • Standard RS-232 serial interface communication.

 

Easy and practical analysis software

  • Easy-to-use AAS analysis software is made under Windows operating system.
  • Automatic curve fitting, automatic sensitivity correction.
  • Automatic calculation of sample concentration (content), mean value standard deviation and relative standard deviation calculation.
  • Multi-elements determination in sequence to the same sample.
  • Measured data and final results can be printed out and edited in Excel format.
