1, the unique design of the new integrated structure will be full PEEK pump head constant high pressure pumps, electric PEEK injection valve, precision column oven, digital thermostat conductivity detection systems, precision column oven and other components are integrated to maximize shorten the connecting pipe, to obtain excellent baseline stability and high resolution capability and very low detection limits. 2,7.0 inch large touch screen with integrated machine design, with a 7.0-inch full touch screen, without any mechanical buttons. Instrument working state parameters, real-time display and real-time spectrum parameter changes and synchronized with chromatography software. 3, all non-metal flow path peek a professional import configuration parts, plastic flow path (including chromatography pumps), metal corrosion dissolution of pollution; has a complete flow path from high and low alarm protection system. 4, complete system monitoring functions using touch screen and PC anti-control software in parallel operation mode, enabling operation carried out simultaneously, along with a sound system monitoring capabilities, running real-time monitoring instruments to facilitate the revision of the operating parameters, integrated set fast halogen Tester, also has data memory protection features, easy to use. Adding halogens (fluorine rohs halogen tester, chlorine, bromine, iodine) in plastics and other polymer products to improve ignition, its advantages are: high flash point than ordinary polymer material, lighted about 300 ℃. When burned, it will emit halogenated gases (fluorine, chlorine, bromine, iodine), rapid absorption of oxygen, so that the fire is out. But its disadvantage is the high concentration of chlorine released when the visibility dropped due to not recognize the escape route will lead to, at the same time highly toxic chlorine gas, affect people's respiratory system Shenzhen halogen tester, in addition, the emissions of halogen-containing polymers halogen gas in combination with steam halogen tester will generate corrosive gases (hydrogen halide), some of the equipment and buildings cause corrosion. PBB, PBDE, TBBPA and other brominated flame retardants are currently using more flame retardant, mainly used in electrical and electronic industry, comprising: a circuit board, computer, fuel cells, televisions and printers. These halogen-containing flame retardant material to produce dioxins when burned, and can exist in the environment for many years, even a lifetime accumulated in the organism, can not be discharged. Therefore, many international companies are actively promoting the complete abolition of halogen-containing materials, such as prohibiting the use of halogenated flame retardants in their products and so on. At present, for halogen-free requirements, different products have different limits: If no halogenated wire and cable wherein the halogen indicators: All values ??halogen ≦ 50PPM (according to regulations PREN 14582); generating hydrogen halide content of post-combustion <100PPM ( According to regulations EN 5067-2-1); PH value of water soluble hydrogen halide produced after combustion ≧ 4.3 (slightly acidic) (according to regulations EN-5 0267-2-2); products after combustion in a sealed container Through beam of light transmittance rate ≧ 60% (according to regulations EN-50268-2). Halogen-free requirements: bromine, chlorine content of less than 900ppm, (bromine + chlorine) is less than 1500ppm.
