Flame/Graphite Furnace Atomic Absorption Spectrophotometer Model AA-7001

Product Description

Advanced graphite furnace power supply built-in design ;
It can be equipped with graphite furnace autosampler to make analysis work easier;
Long life graphite tube, can be used for a long time at 2000℃ ;
Automatic control of the graphite furnace program temperature rise, up to 20 steps ;
Flexible deduction background design, high salinity, high background samples (such as soy sauce, food, etc.) can also get reliable analysis results.

Optical system suspension design, vibration, ambient temperature changes do not affect the stability of the instrument.
The world's first flame atomizer/graphite furnace atomizer, graphite furnace power supply and optical and electronic detection systems are all integrated into the same instrument body, which is one of the most compact AAS in the world.
The first full titanium atomized combustion system in China. Adopting aerospace high-tech, lost wax precision casting industrial pure titanium atomization chamber and combustion head, with excellent corrosion resistance, oxidation resistance, high temperature resistance, long service life.
The first in China to adopt 1800 lines/㎜ diffraction grating with sufficient energy and high resolution.
Single-beam optical system with low detection limits for elements such as arsenic and selenium with sufficient energy.
Fully automatic flame/graphite furnace switching in two seconds.
Carefully designed tritium lamp buckling background technology and self-absorbing full band buckling background technology for more accurate calibration results. Optimized power supply technology extends lamp life.
Safe and reliable control and alarm devices ensure overcurrent protection of hollow cathode lamps, gas/protective gas underpressure protection, gas leakage alarms, graphite furnace overheating protection, and flame abnormal state protection.
It can be equipped with the first domestic HG-01 ceramic heating tube hydride generator to analyze As, Pb, Se, Hg and other elements with high sensitivity and accuracy.
It can be equipped with graphite furnace autosampler, automatic preparation of standard solution to realize fully automatic analysis.
