河南快3500: Melamine On-Site Rapid Detection Kit

Melamine is a synthetic organic nitrogen-containing heterocyclic compound with high nitrogen content (up to 66%), and its production process is simple and the cost is very low. When the crude protein is determined by kjeldahl nitrogen method, it can increase the content of apparent crude protein. In order to reduce production costs and improve economic efficiency, illegal producers illegally added melamine in raw milk and other production and processing links. A large dose or long-term intake of melamine can cause damage to the reproductive and urinary systems, bladder and kidney stones, and can further induce bladder cancer.

Detection range of diagnostic rapid test kit
1. Solid samples: solid samples of feed, feed materials, milk powder, cake, milk tea powder, etc.
2. Liquid samples: liquid raw milk, yogurt, chocolate milk, coffee milk and other liquid milk products.
3. Fresh eggs, etc.

Matters to be noticed
& Oslash; place the reagent in a cool and dry place at room under the temperature of 4-30 ℃ and preserve in normal temperature, valid for 1 year.

& Oslash; Melamine reagents B, C and D can be fixed using the corresponding straw, do not cross - use. 5mL centrifugal tube and solid phase extraction column shall not be reused.

& Oslash; When the liquid is in the supersolid phase extraction column, if the phenomenon of column plugging is found, the corresponding extraction column will be invalid.

& Oslash; When the supernatant is absorbed according to step 1, the suction head is located on the surface of the liquid surface to prevent the sediment from inhaling, resulting in the blockage of the extraction column.

& Oslash; In the process of solid-phase extraction and purification, it is important to control the liquid flow rate.

& Oslash; Raw milk is easy to acidify at room temperature. 4 ℃ refrigerator 48 hours of raw milk should be complete detection. If local agglomeration and foaming changes are generated, the preliminary screen cannot be used.

& Oslash; Using vortex mixer for extraction and extraction, the extraction and extraction results will be better.

& Oslash; If a suspected positive sample is detected, it is recommended to confirm it further in the laboratory using an instrument.

& Oslash; In the use of reagents, attention must be paid to safety, if not careful to splash reagents on the skin, immediately with clean water.
