Introduction: SK-2003A atomic fluorescence spectrometer is widely used in food, medicine, cosmetics, feed additives, water, soil and other fields of arsenic, mercury, lead, selenium, cadmium and other heavy metals for trace analysis spectrometer. SK-2003A is SK-2002A upgrade model, SK-2002A single-channel power supply to dual power supply, the regulatory agencies to the scale of three-dimensional orbit, the reaction module to A-type defoaming multi-functional reaction Module. SK-2003A with the test speed, good technical indicators, cost-saving supplies and other characteristics. The instrument tested three times a sample of data only 30 seconds, better than other similar products on the market. In addition, SK-2003A's technical indicators better than the national standard, for the instrument stable and accurate testing laid the foundation. The streamlined structure of the instrument reduces the need for instrument components, thereby reducing the cost of consumables. Applications: Teaching and research, health and epidemic prevention, medical clinical examination, drug testing, food hygiene inspection, urban water supply and drainage inspection, agricultural product inspection, beverage inspection, environmental monitoring, cosmetics inspection, metallurgical sample inspection, geological survey and so on. Features: 1, injection system Using the latest special big wheel single-pump dual-channel injection technology, both to achieve the traditional injection mode, but also to achieve Jin Sukun invented patented technology of continuous flow injection mode. Making the pipeline path is short, the memory effect is small; the connection is simple, easy to operate, easy to maintain. 2, hydride generation system The hydride generation system uses the A-type multi-functional reaction module with Jin Suo Kun patented technology. The module is highly integrated hydrogenation reaction, gas-liquid separation, waste removal and other functions in one. Among them, the precise reaction chamber with the function of breaking bubbles makes the reaction of hydrogenation smooth. The pressure in the module of self-balance type waste liquid discharge device not only simplifies the pipeline but also reduces the point of failure so as to achieve a high degree of balance between injection, reaction and waste discharge. The gas-liquid separation technology utilizing the principle of cyclone, gravity and Adam's apple junction makes the gas-liquid separation completely, which lays the foundation for obtaining the high repeatability index of the whole machine. 3, pneumatic transmission system The gas transmission chamber with Kim Sok-kun patented technology greatly shortens the pipeline and effectively eliminates the memory effect, and at the same time enables the hydrogen generated by the hydrogenation reaction to be fully mixed with the gas under test and the carrier gas for transmission to the atomizer. For the measured elements can be efficient atomization laid the foundation. 4, atomization system Streamlined atomizer with steady current, dry, low temperature auto-ignition and high efficiency double-layer shielded system reduces the fluorescence quenching and gas phase interference and improves the atomization efficiency. In addition, three-dimensional adjustable atomizer adjustment mechanism can be up, down, left and right, front and rear three-dimensional more convenient, fast and accurate adjustment atomizer position, so as to achieve the best excitation effect. 5, light system Using Jin Suo kun characteristics of the short focal length non-dispersive optical path system, compared with the use of short-focal length optical system received fluorescence signal intensity increased by 2.8 times. 6, the circuit system Among them, the light source control part adopts adjustable duty cycle dual pulse power supply, and different duty ratios can be selected according to different elements of the test, which not only improves the intensity of the high performance hollow cathode lamp but also prolongs the service life of the lamp. The use of Kim Soon Kun patented large-scale integrated circuits operate fast, anti-interference ability, to achieve no inter-channel interference. 7, design The use of the international popular 3U chassis design, the overall structure is simple, easy to operate, with good electromagnetic compatibility. Specifications: Test element As Sb Bi Pb Sn Te Se Zn Ge Cd Hg Detection limit (DL) ng / mL <0.01 <1.0 <0.05 <0.001 Repeatability (RSD) <0.6% The linear range is greater than three orders of magnitude Road interference 0
