Product overview: At present, it is recognized that the human body needs a total of 14 trace elements, specifically zinc, copper, iron, manganese, tin, cobalt, molybdenum, nickel, vanadium, selenium, chromium, silicon, fluorine and iodine.Calcium and magnesium in the blood and hair mediates between trace and macro.Lead, mercury, cadmium, aluminum are clearly harmful to human DS-3A microelement analyzer is an electrochemical microelement detection instrument capable of most of the above elements detection. Test sample type: total blood 40 microliters, hair 0.1, other such as urine, water, food and beverage, solid samples, etc. Test items: normal zinc, copper, iron, calcium, magnesium and lead can be added to the test items according to users' requirements. Technical features: It has the function of electrochemical polarography and electrochemical dissolution, and USES the most suitable function to detect different elements. Double electrode system USES patent static mercury electrode technology and imports of glassy carbon electrode, conforms to the WS/T21-1996 and the ministry of health inspection procedures prescribed methods measuring blood lead, using whole blood standard calibration instruments, results are accurate and reliable, whole blood there is no direct detection convenient and quick, reagent consumption, lower testing cost, a number of innovative patent support, instrument repeatability, stable performance and reliable results. Features: low price, excellent performance, beautiful appearance. It is especially suitable for users below the county level. Technical parameters: Compatible electrode: static mercury electrode (patented product), glasscarbon electrode. Foremost analytical method and function: potential polarographic function, volt-ampere polarographic function, potential dissolution function, volt-ampere Dissolution function. Applications: zinc, iron, copper, calcium, magnesium and lead in whole blood (or hair) The bottom half of the scans: 0.1 microgram per liter (with lead as an example) The solubility variance coefficient: RSD is less than 5% The solution-related coefficient is greater than or equal to 0. 99 Relative deviation of the solubility correction curve: less than 10% (take lead measurement for example) The unity antinuclear ability: 5000: l Inspection methods: lead is detected by differential potential dissolution or anode dissolution. Zinc, iron, calcium, magnesium and copper were measured by polarography.
