Rapid quantitative testing kits for Copper
Determination of copper in rice, corn, beans, wheat and other food crops and feeds
Product introduction
Copper is an indispensable mineral in human body, which has a significant impact on the development and function of human organs. However, excessive intake of copper has certain harm to the body, such as severe renal damage and hemolysis, jaundice, anemia, hepatomegaly, hemoglobinuria, acute renal failure and uremia, so it is necessary to detect heavy metal copper.
1. Kit description
This product is a rapid detection kit for heavy metal copper, which is used for quantitative detection of heavy metal copper content in rice, corn, beans, wheat and other food crops. The national limit of heavy metal copper is 10mg / kg (PPM) (obsolete).
2. Principle of kit
The sample was crushed, weighed, extracted with extractant, centrifuged and added with sample diluent to chelate heavy metal ions in the supernatant. Add the sample liquid to the sample pad, chromatography along the direction of the kit to the absorbent paper, the heavy metal ion chelate binds with the colloidal gold labeled monoclonal antibody on the colloidal gold binding pad, the unbound colloidal gold labeled monoclonal antibody specifically binds with the whole antigen corresponding to the heavy metal on the detection line t and is partially intercepted, showing a red band. When the gold labeled monoclonal antibody flows through the quality control line C, part of it reacts with Goat anti mouse IgG on the quality control line C and is intercepted, showing a red band. The color of the detection line t is determined by the instrument, and compared with the standard curve preset in the instrument, so as to accurately determine the content of metal ions.
3. Detection range
Quantitative determination of copper content in rice, corn, beans, wheat and other food crops.
Quantitative detection range: 0-50ppm
