Specifications
The BFRL WFX-860B Pro Zeeman AA Spectrophotometer is an advanced analytical instrument designed for elemental analysis and quantitative determination of metals and other measurable elements in various sample types. It combines Zeeman background correction technology, a double-beam optical system, and an automatic flame atomization system to support accurate, stable, and reliable analytical performance.
Equipped with an automatic 8-lamp turret, intelligent lamp optimization, and a Czerny–Turner monochromator, the WFX-860B Pro provides flexible analytical operation across a wide wavelength range. Its constant and transverse magnetic field Zeeman background correction system helps reduce background interference, including interference above 2 Abs, according to the manufacturer.
The instrument features automatic ignition, precision gas-flow control, intelligent flame adjustment, and safety monitoring. Its operating software supports automated instrument optimization, calibration curve fitting, concentration calculations, and multi-task analysis. Ethernet connectivity provides stable communication with the control computer.
