Main characteristics: Unique light path design Reliable flame safety system Automatic four-lamp turret system Small flame structure analysis system Multi-Functional software working station Micro-computer automaticly control operation system Multi-functional flame atomic system High efficent and sensitive stomic system Introduction: Built-in computer data processing and liquid crystal display: A highly integrated PC-based digital circuits, stable and reliable. It has integral to maintain, peak height, peak area, automatic zero adjustment, deuterium lamp background deduction, a variety of linear and nonlinear curve fitting, the screen shows the various parameters and working curves, print reports and other functions, also with an external personal computer interfaces. Reliable baseline stability: dual-beam system of optimal design can compensate light source drift, wavelength drift caused by temperature changes (with the function of eliminaing the baseline stability caused by wavelength drift) and the electronic circuit drift, therefore, has a reliable baseline ***** lamps can analyze sample immediately without long-term ***** is firstly chosen equipment for users to analyze the various elements and rapid analysis of samples High precision: Gas system can ensure high precision of test and low concentration as it is equipped with sophisticated regulation, steady flow devices, the thin beam of unique designed running through the flameIt is stable flame and low noise, High-energy light path: reflective optical system, the whole waveband achromatic. Transform optically the circular light beam into a long beam and run into the slit, thus enhancing the optical flux of two-beams. Long-life corrosion-resistant atomic system: combustion head is made of new titanium alloy material which is corrosion-resistant, fast heat balance , can achieve measurement sensitivity stability no water cooling. Multi-functional analysis mode: for methods of flame absorption, flame emission, graphite furnace atomic absorption and hydride generation. Safe and reliable gas system: fast gas switching and security guards, can make the analysis of air - acetylene flame as well as nitrous oxide flame, expanding the elements to more than *0 species.
