The specially designed digestion device can significantly improve the digestion efficiency. It has powerful functions, high automation, high sensitivity and high reliability. Successfully passed the product technology appraisal organized by the China Instrument and Meter Industry Association, and won the 2015 Independent Innovation Silver Award. Application areas: Food hygiene inspection, environmental sample inspection, water sample inspection, geological and mineral sample inspection, agricultural inspection, clinical inspection, education and scientific research. Features: 1. Suitable for trace analysis of arsenic, mercury, selenium, lead, germanium, tin, antimony, bismuth, cadmium, tellurium, zinc, gold and other elements in samples. 2. Simultaneous measurement of dual channels and two elements. 3. Light source: dual-position hollow cathode lamp, pulse power supply mode. 4. Optical system: dual-channel short focal length lens condenses light, and has a device to remove stray light. 5. With automatic deduction circuit for inter-channel interference and DC drift, reduce instrument drift and improve instrument stability. 6. Adopting the built-in intermittent flow sampling device combined with the imported syringe pump and the peristaltic pump, which not only ensures the accuracy of the injection volume, but also overcomes the corrosion and leakage of the syringe pump. At the same time, samples and blanks are introduced alternately, online cleaning, Power to remove waste liquid, prevent cross-contamination, and save the amount of samples and reagents. 7. Atomizer: argon hydrogen flame, shielded quartz furnace atomizer. 8. Gas circuit system: It has automatic gas circuit protection device, which can automatically control the gas circuit and automatically diagnose, and automatically control the gas flow. 9. Fully automatic and intelligent operation, disc auto sampler, single sample tray up to 183 positions. 10. The instrument can realize a single-point configuration working curve and automatically dilute high-concentration samples. 11. The circuit system adopts the separation of strong and weak electricity, and the highly integrated modular electricity design makes maintenance more convenient. 12. Dedicated Windows/2000/7/8 system operating software, with a powerful expert online help system. 13. The software can quickly import measurement data into EXCEL, and realize network resource sharing. 14. Equipped with trap device, which can absorb harmful exhaust gas emitted by the instrument.
