  Basic Features: 1. Built-in computer data processing and liquid crystal display: using highly integrated microcomputer digital circuit, stable and reliable. With integral hold, peak height, peak area, automatic zero adjustment, deuterium lamp buckle background, a variety of linear and non-linear curve fitting, screen display of various parameters and working curves, print reports, etc. At the same time, it has an external personal computer interface. 2. Reliable baseline stability: The optimized dual-beam system can compensate for light source drift, wavelength drift caused by temperature changes (with the function of eliminating the effect of wavelength drift on baseline stability), and electronic circuit drift, so it has reliable baseline stability. The cathode lamp can analyze samples immediately without long-term preheating. It is the instrument of choice for users who analyze a variety of elements and quickly analyze samples. 3. High-precision measurement: Because the gas system is equipped with precise voltage stabilization and flow stabilization devices, the flame is stable, the noise is low, and the thin beam of unique design passes through the flame to ensure high precision and low characteristic concentration of the analysis test. 4. High-energy optical path: adopting total reflection optical system, achromatic in the full band, and transforming the circular light spot of the light source into a long light spot into the slit, thereby improving the light flux of the two beams. 5. Long-life and corrosion-resistant atomization system: The combustion head uses a new type of titanium alloy material that is resistant to corrosion and rapid thermal equilibrium. It can meet the requirements of stable measurement sensitivity without water cooling. 6. Multifunctional analysis methods: flame absorption, flame emission, graphite furnace atomic absorption (with AS-3020 autosampler can be equipped) and hydride generation method. 7. Safe and reliable gas circuit system: with fast gas switching and Safety protection device. 8. Complete accessories: complete random accessories, ready to use after purchase. 9. Optional data acquisition software and brand computer   Over the past 20 years, we have gained the trust and support of many customers. Our company has established close cooperative relations with many world famous brands, providing high-quality products and pre-sales and after-sales services for the scientific research and development of all walks of life.
