Atomic Absorption Spectrophotometer

features:
. phase difference corrected monochromator, provide optimized optical path for entire wavelength.
. built-in 6 lamp turret, with 2 lamps (operation lamp and preparation lamp) simultaneously lightening.
. equipped with innovative and unique deuterium background correction (patent pending) for entire wavelength range.
. combustion gas cooling burner head is innovated newly and is applying patent. this technique could reduce much heating balancing time at the burner head.
. high safety air-acetylene flame facilitates 35 common elements analyzed at low operation cost.
. genius database system allows you to access index and abstracts of large amount of chinese and english literature.

complete automation on
. alignment and fine adjustment in hollow cathode lamp position.
. wavelength scan control and peak search and slit width se-lection.
. optimization of photomultiplier gain.
. energy balance between deuterium lamp and hollow cathode lamp.
. flame ignition (on/ off) as well as acetylene-o2 gas flow rate setting to optimize combustion ratio.
. optimization of analytical conditions for se-lected element simply by a mouse-click while six elements can downloaded simultaneously.

high safety
. fully automated gas control and integrated safety check yield the safest flame aa system available today.
. incorporated with air pressure sensor, acetylene gas flow will be cut in case of accident.
. combination of safety-designed burner head, special drainage system and pressurized valve control spray chamber.
. with presence of high pressure gas leakage check, it ensures automatic disconnection of gas lines in case of acetylene build up accidentally.
