WFX-210 Atomic Absorption Spectrophotometer
1. Innovated flame analysis technique
2. 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.
3. Popular Czerny-Turner grating monochromator with 1800l/mm provides higher resolution.
4. All plastic pre-mix spray chambers with high anti-corrosion ability.
