Description

SP-IAA1800H atomic absorption spectrometer is widely used in scientific research, quality inspection, disease control, environmental protection, metallurgy, agriculture, forestry, chemical industry and other industries, innovative software and hardware design to ensure the accuracy of the sample analysis, safety, ease of use, simple and convenient instrument maintenance.

Features

  • High precision fully automatic optical system

Large area grate with 1800 lines/mm dispersion rate, novel self-collimating monochromator, all lense are Shi Ying coated, wide detection range and optical stability ensure that accuracy of analysis. Automatic 6 lamp holder equipped with 6 independent lamp power supply, can respectively preheating.

  • Polymer atomizing chamber

High-molecular material anti-corrosion atomization chamber, acid and alkali resistant, including hydrofluoric acid, whether organic or inorganic solution can get better sensitivity and stability.

  • Titanium burner

Titanium burner, optional 50mm and 100mm burner, air cooling pre mixed type, corrosion resistance, high salt resistance, greatly improve the efficiency of the flame and flame analysis accuracy.

  • Fully automated analysis

It can automatically complete safe ignition, extinguishing and switching, with reliable structure and low failure rate, thus ensuring the sensitivity and repeatability of the flame method;The light source system automatically switches the six-lamp-position platform, can directly use the high-performance hollow cathode lamp, improves the sensitivity of flame analysis, automatically adjusts the power supply parameters and the beam position, and fully automatically scans and searches for the wave crest.

  • Graphite furnace temperature control

Double temperature control of internal and external air, 20-order linear or nonlinear temperature rise, to ensure that the elements to be tested have good sensitivity; Enrichment and concentration were carried out for 20 times in the furnace. The inner wall temperature of the graphite tube was monitored by longitudinal light control, and the maximum temperature could be increased to 3000 C/s.

  • High technology index

The element test sensitivity of AA-1800 atomic absorption spectrometer reaches the advanced level in the industry, with the sensitivity ≤0.015 µ g/mL/1%; Baseline drift less than 0.003Abs/30m with better stability than 0.005Abs/4h.

  • Background correction system

The deuterium hollow cathode lamp and the self-absorption button background are adopted for background correction, so that the interference of molecular absorption in the determination of low content is eliminated, the emission noise of the deuterium lamp is reduced, the service life is prolonged, and the deuterium hollow cathode lamp has good stability. When the background signal of deuterium lamp is 1A, the background subtraction ability is > 50 times.

  • Intelligent analysis

Intelligence is very strong, humanized design, flame and graphite furnace atomization device automatic switching, graphite furnace atomization device automatic optimization, automatic setting to adjust the flame height, automatic ignition, automatic optimization of horizontal position, the system automatically set the gas flow. In case of power outage, misoperation, acetylene leakage, etc., the system will automatically start the safety protection function;

  • Automatic sampler

Integrated with graphite furnace, high-precision injector was used, and the minimum volume of sample could be 0.5 µL. The intelligent online dilution and concentration function was realized.
