Product details:
Performance characteristics: 1. Integrated design of flame graphite furnace, built-in power supply of graphite furnace and auxiliary gas design reduce the influence of sample introduction on flame state and atomization temperature, which is more suitable for accurate analysis of organic samples and small lift samples. 2. The power of graphite furnace is controlled by current and voltage vector to ensure high reproducibility of temperature rise of graphite furnace. 3. The optimized EMC circuit design including EMI (electromagnetic interference) and EMS (electromagnetic tolerance) ensures the reliable and stable operation of the instrument circuit. 4. Czerny turner type optical path design, short optical path, strong energy. 1800 reticles/mm plane diffraction gratings are adopted, with high resolution. 5. Fast heating rate: ≥ 2000 ℃/s, with multiple safety detection measures: temperature detection of graphite furnace body, cooling water pressure detection, inert gas pressure detection, graphite tube fracture or unclamping detection. 6. Graphite furnace/flame switch adopts adjustable pneumatic device, which makes atomic absorption work mode complete in one click. 7. The vertical 8-element lamp design avoids the lamp position drift caused by the parallel lamp design. 8. The floating optical platform ensures the high mechanical stability of the instrument and greatly reduces the weight of the instrument. 9. The elaborately designed graphite furnace automatic sampler ensures the high-precision positioning (0.1%) of the graphite furnace sampling probe. 10. The slit, wavelength and ignition of the instrument are controlled by one key. 11. It has perfect safety interlock protection device and anti backfire device. In case of power failure, gas failure and other accidents, the instrument automatically cuts off the gas. Technical indicators:
