GGX-830 flame graphite furnace integrated atomic absorption spectrophotometer

Performance characteristics:
1. The integrated design of flame graphite furnace, with built-in graphite furnace power supply and auxiliary gas design, reduces the influence of sample introduction on flame state and atomization temperature, making it more suitable for precise analysis of organic samples and small lift samples. 2. The power of graphite furnace is controlled by current voltage vector to ensure high reproducibility of graphite furnace heating. 3. The optimized EMC includes EMI (electromagnetic interference) and EMS (electromagnetic tolerance) circuit design, ensuring reliable and stable operation of the instrument circuit. 4. Czerny turner type optical path design, with short optical path length and strong energy. Using 1800 engraved lines/mm plane diffraction grating, with high resolution. 5. Fast heating rate: ≥ 2000 ℃/s, with multiple safety detection measures: graphite furnace body temperature detection, cooling water pressure detection, inert gas pressure detection, graphite tube fracture or unclamped detection. 6. The graphite furnace/flame switching adopts an adjustable pneumatic device, which enables the atomic absorption working mode to be completed with one click. 7. The vertical 8-element lamp design avoids the phenomenon of lamp position drift caused by parallel lamp design. 8. The floating optical platform ensures high mechanical stability of the instrument while greatly reducing its weight. 9. The carefully designed graphite furnace automatic sampler ensures high-precision positioning (0.1%) of the graphite furnace injection needle for injection accuracy. 10. The control of instrument slit, wavelength, ignition, etc. can be completed with one click. 11. Equipped with comprehensive safety interlock protection devices and anti backfire devices, the instrument automatically cuts off gas in case of unexpected situations such as power failure or gas interruption.
