การดูดซับค่าโดดสเปคโตรมิเตอร์ (HHG9602A)

HG9602A atomic absorption spectrometer

As a creation, hydride technology and atomic absorption are integrated in an instrument, it matches with hollow cathode lamp with high performance (special power supply is equipped in the instrument), electric heat quarts atomization apparatus and flame cut unit in atomization apparatus and auto-zeroing and auto-capture technology by the computer, get the sensitivities of mercury, arsenic, selenium, antimony, tin tellurium, bismuth that measured by atomic absorption apparatus to be small than 0.5 ng/ml/1%A, the precision is small than 5%, the consumption of once measured sample is small than 2 ml, the measured speed for sample can be up to 100 times/hour. It can be widely applied in environmental protection, epidemic control, commodity inspection and quality inspection field etc.

Completion function
The instrument has the functions of atomic absorption, flame emission (being able to instead of flame photometer), deuterium lamp background correction, automatic zero setting, automatic ignition, automatic wavelength scanning and 586 computer data processing.

The rotating lamp holder is able to fit and preheat 4 elemental lamps at one time, and is also able to fit and preheat 2 high performance elemental lamps (of state patent technology) at one time.

Can be directly connected to graphite furnace atomizing device. And upgrade the testing sensitivity to 3 orders of magnitude than flame AA of more than 70 elements.

Can be directly connected to Enrichment Apparatus and effectively enrich Cu, Zn, Pb, CD, Mn, Ni etc more than 20 elements. Combine with the peak value testing method, it can bring up the testing sensitivity 200 times. It also can implement directly trace element testing among the sea water, underground water and surface water.

Good reliability
The host machine of the instrument is furnished with complete circuit measuring system and the host machine data acquisition and processing are performed by computer, forming two sets of independent working systems, one instrument working system and one computer working system, casting off the dependence of the instrument upon the computer, and hence raising the reliability of the instrument. When the computer stops working, the instrument can still be running separately.

The host machine circuit concentrates the imported integrated components on one circuit board, making circuit board be of high integration, low failure rate and easy maintenance. The user can achieve the purpose of repairing the instrument through posting the circuit board by mail service.
Advanced software design
The data processing system of the computer adopts the multi-window processing technology under 586 general purpose computer, being able to display measurement parameters, establishing performance curves, measuring sample concentration and printing and storing data.
Compact structure
The instrument concentrates years of atomic absorption design experience and rationally combines various components, being furnished with monochrometer of short focal length, hence making the instrument compact in structure and elegant in appearance.
Perfect safety
In case of sudden power suspension or insufficient air pressure during operation which is liable to cause backfire of acetylene, the instrument can automatically cut off acetylene gas for protection of the instrument.
