Introduction: BAF-4000 atomic fluorescence spectrometer is mainly used for environmental sample testing, food hygiene inspection, water sample inspection, agriculture and its product testing, geological metallurgical sample testing, disease control and epidemic prevention center sample testing, Chinese and Western medicine, biological materials, cosmetics, textile clinical Fields of experimentation and educational science research. 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 antimony (Sb) can be detected. Features: 1. Simultaneous determination of three elements - in line with high efficiency and environmental protection requirements, more suitable for users with large sample size 2. Unique design of small angle light path - stray light to the lowest, low background high signal; and channel enhancement 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 - light source auto focus does not need manual adjustment, ordinary element light is plug and play; with mercury lamp self-exciting function, no auxiliary tools to stimulate the radiance 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--Double syringe pump injection system, syringe pump and peristaltic pump mixed sample introduction system, peristaltic pump sample introduction system, etc., various ways for users to choose according to requirements: (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) Import and assembly of high-precision syringe pump and peristaltic pump mixed sample introduction system, the use of syringe pump can accurately control the solution intake and the speed of the peristaltic pump injection system, which greatly improves the working efficiency and is suitable for a wide range of samples. 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 working platform - software operation is simple; has method file library; has system self-diagnosis and fault point self-detection function; can update firmware online. 11. The instrument uses LAN/WIFI communication interface - for quick control and stable operation; Technical indicators: Three-way simultaneous precision (RSD): RSD ≤ 0.6% (As, Sb, Bi, Hg); Representative 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.
The BAF-4000 atomic fluorescence spectrophotometer is mainly used to detect arsenic, mercury, selenium, antimony, bismuth, lead, Contents of twelve trace elements such as germanium tellurium, cadmium, tin, zinc, and gold. After the upgrade, arsenic (As), mercury (Hg), selenium (Se), antimony (Sb) and other elements can be detected. BAF-4000 Atomic Fluorescence Photometer is commonly used in environmental sample testing, food hygiene inspection, water sample inspection, agricultural and product testing, geological metallurgy sample testing, CDC sample testing, Chinese and western medicine, biological materials, cosmetics, and textile clinical experiments And educational scientific research.
