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
