IAFS-100 Fully Automatic Alkyl Mercury Analysis System Introduction: Alkyl mercury is a highly toxic and carcinogenic organic mercury compound, widely present in atmospheric, water, and soil environments. Due to their lipophilicity, bioaccumulation, and biomagnification effects, these compounds are hundreds of times more toxic than inorganic mercury. Alkyl mercury is represented by methylmercury and ethylmercury, with methylmercury being the most toxic. Any form of mercury in the environment can be converted to methylmercury under certain conditions. The iAFS-100 fully automatic alkylmercury analysis system measures the content of trace alkylmercury such as methylmercury and ethylmercury in samples through distillation treatment, blowdown capture/gas chromatography atomic fluorescence method. The instrument can achieve fully automated operation, accurate measurement results, low detection limit, and wide measurement range, making it the best instrument for measuring alkylmercury. Technical features: 1. Adopting a fully automatic XYZ 3D robotic arm sampler for precise positioning 2. Adopting a passivated stainless steel double-layer sampling needle with a spacer puncture function and no sample adsorption 3. High throughput: Comes standard with 72 bits. Multiple specifications of automatic samplers including 36 bit, 72 bit, or 108 bit are available for selection 4. Blowing method: Dual modes of ectopic and in-situ blowing are available, with ectopic blowing as standard 5. Use Tenax trap to capture target samples, with dedicated trap packing and heating and cooling technology to ensure excellent adsorption/desorption efficiency 6. Surrounding heater pulse heating, reverse analysis of samples, fast heating speed, good peak shape 7. High temperature cracking column: can be heated to above 750 ℃ to ensure rapid decomposition and reduction of different forms of mercury into vapor mercury 8. The system comes standard with an exhaust absorption device, which prevents mercury vapor from being emitted into the air and is environmentally friendly 9. Using a low-pressure mercury lamp as the light source, the pulse constant current driving method ensures stable light intensity output and low noise 10. Adopting a non dispersive proportional dual beam detection method, the light source signal and fluorescence signal are simultaneously measured by differential operation of the sample to ensure optimal stability and sensitivity 11. Linear range of methylmercury: 0-25ng/L; Linear range of ethylmercury: 0-25ng/L 12. Detection limit of methylmercury: better than 0.003ng/L; Detection limit of ethylmercury: better than 0.003ng/L 13. Windows Chinese user-friendly interface, capable of editing sequences, automatically analyzing data, importing standard curves, and other operations 14. The instrument parameters can be directly modified and controlled through the control software, which is simple and convenient 15. It has two data processing methods: least squares method and response factor method
