Introduction: Application areas: mainly used for environmental sample testing, food hygiene inspection, water sample inspection, agriculture and its product testing, geological metallurgy sample testing, disease control and epidemic prevention center sample testing, Chinese and Western medicine, biological materials, cosmetics, textile clinical trials and educational science Research and other fields. Test object: Atomic fluorescence photometer is mainly used to detect arsenic, mercury, selenium, tellurium, antimony, lead in samples of food, agricultural products, tap water, surface water, sea water, Chinese and Western medicine, biological materials, cosmetics, textiles, metallurgy and geology. The content of twelve trace elements such as bismuth, cadmium, tin, zinc and gold. After upgrading, the morphology of elements such as arsenic (As), mercury (Hg), selenium (Se), and (Sb) can be detected. Features: 1. Simultaneous determination of two elements - meeting high efficiency and environmental requirements 2. Advanced small-angle light path - stray light is reduced to the lowest, low background high signal; and channel enhancement function; 3. Light source buckle drift system--With continuous light source monitoring device, it automatically corrects the drift of mercury lamp to ensure long-term stability of the instrument; 4. Element light source is free of adjustment - the light source auto focus does not need to be manually adjusted, the common element lamp is plug and play; and has a self-excitation function of the mercury lamp, which does not require an auxiliary tool to stimulate the glow; 5. High-precision gas path control--Adopting advanced dual-channel mass flowmeter to control carrier gas and shielding gas, the gas flow is reliable and stable, real-time monitoring of gas flow, no carrier gas safety protection; shutdown can automatically cut off the gas path, effectively reducing argon Gas consumption; 6. Fully automatic double injection system--Multiple syringe pump injection system, syringe pump and peristaltic pump mixed sample introduction system, peristaltic pump injection system, various ways for users to choose according to their needs: (I) The dual-injection pump assembled with imported components has precise control of solution intake (including sample and reducing agent solution volume) and high intelligence. It is suitable for detecting the rigorous elements of hydride reaction pH requirements (Pb, Cd, Sn, etc.) It is also suitable for the detection of other rare samples. (II) The high-precision syringe pump and peristaltic pump mixed sample introduction system for the assembly of imported parts, the injection pump can accurately control the respective advantages of the solution intake and the fast sampling speed of the peristaltic pump injection system, significantly improve the work efficiency and be suitable for comparison. Wide sample detection. (III) The peristaltic pump sampling system is a classic injection method that is easy to grasp. It has the characteristics of high speed and high efficiency, and is suitable for turbidity, complex matrix and wider sample detection. 7. Fully automatic standard addition system--For the samples with complex matrix interference, the standard addition method module can be selected, that is, the standard solution of the sample to be tested is automatically added online, automatic mixing and automatic measurement, which greatly reduces the workload of the experimenter. increase work productivity. 8. Intelligent liquid level detection technology--automatic detection of the liquid level of the sample in the test tube, intelligent tracking with the amount, control the depth of the injection needle liquid surface to avoid cross-contamination of the sample; the injection needle is corrosion-resistant, high-strength, hydrophobic The special metal material that does not touch the liquid overcomes the shortcomings of the traditional glass syringe easy to break and easy to hang liquid. 9. Ultra-quiet polar coordinate autosampler--Efficient large turntable automatic sample introduction system, with more than 200 sample positions on a single disk, meeting different user needs; 10.Intelligent work platform--software operation is simple; it has method file library; it has system self-diagnosis and fault point self-test function; 11. The instrument uses LAN/WIFI communication interface--fast communication speed and strong stability; firmware can be updated online. Technical indicators: Dual-channel simultaneous precision (RSD): RSD ≤ 0.5% (As, Sb, Bi, Hg); Typical element detection limits (As, Sb, Bi, Hg,): ≤ 0.01 μg / L; Cold mercury detection limit (Hg): ≤ 0.001 μg / L; Linear range: greater than three orders of magnitude.
