Basic Features:
● Built-in computer data processing and LCD display: Highly integrated microcomputer digital circuit, stable and reliable. With integral hold, peak height, peak area, auto-zero, deuterium lamp buckle background, a variety of linear and non-linear curve fitting, screen display of various parameters and working curves, print reports, and other functions, at the same time with an external personal computer interface.
● 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 the sample immediately without long-term preheating. It is the instrument of choice for users who analyze multiple elements and quickly analyze samples.
● 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 uniquely designed thin beam passes through the flame to ensure high accuracy and low characteristic concentration of the analytical test.
● High-energy light path: adopting total reflection optical system, achromatic in the full band, and transforming the circular spot of the light source into a long spot into the slit through optical transformation, thereby improving the light flux of the two beams.
● 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.
● Multifunctional analysis methods: flame absorption, flame emission, graphite furnace atomic absorption (with AS-3020 autosampler can be equipped) and hydride generation method.
● Safe and reliable gas system: fast gas switching and safety protection device.
● Complete accessories: complete random accessories, ready to use after purchase.
● AA320NCRT comes with a brand computer and data acquisition software.
