AA-1800EL flame/graphite furnace integrated atomic absorption spectrophotometer is a Macylab solely R&D, manufacturing and exclusively selling high-performance, high-reliability spectroscopic instrument, integrated with both flame and graphite furnace atomizer, by use of a computer for the instrument control and data processing through USB 2.0 standard port. This instrument is designed with a tandem optical path structure, the switching between the flame and graphite furnace mode is free of mechanical operation, thus avoid the position deviation caused by mechanical switching, therefore, this instrument is working stably and reliably.
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
