Main features
High precision automatic optical system
1800 / mm reticle (dispersion rate) large area grating
monochromator, a new type self collimation, all lenses are quartz
coating, the detection range and the stability of optical broad to
ensure the precision of analysis. Automatic 8 socket configuration
8 independent lamp power supply, can be
respectively preheating
Polymer spray chamber
Polymer materials corrosion spray chamber, acid and alkali
resistance, includinghydrofluoric acid, either organic or inorganic
solution can be the highest sensitivity andstability
Titanium burner
Titanium burner, the optional 50mm and 100mm burner, air cooling
pre mixed type,corrosion resistant, resistant to high salt, greatly
improve the analysis efficiency andaccuracy of the flame
Automatic analysis
It can automatically accomplish safety ignition, extinction and
switching, reliable structure,low fault rate, thus ensuring the
sensitivity and reproducibility of the flame method.
The light source system six lamp automatic conversion, can be
directly used high performance hollow cathode lamp, improve the
sensitivity analysis of the flame, the automatic
adjustment of the power supply parameters and the beam
position, automaticwavelength scanning and searching peak
Software function
High intelligent software, powerful function, friendly interface
English operation.Automatic instruments and additional control,
flame, graphite furnace operating mode can be switched
automatically, automatic optimization, automatic dilution; mouse
operation, automatic setup menu data and correction method
