Melamine is an important organic chemical intermediates, mainly used to produce melamine resin, has an excellent water resistance, heat resistance, arc resistance, excellent flame retardant. Can be used for the production of decorative panels for the amino plastics, adhesives, paint, paper currency strength, such as auxiliaries. Melamine is currently seen as slightly toxic, but in 2007, the United States have been incidents of pet food ingredients containing melamine led to the poisoning of animals, after investigation, two of China's raw pet food companies add due to irregularities. It is reported that the addition of melamine products, components can increase the apparent protein content of the product, which is illegal in many enterprises to add the element of the main reasons.
Since 2007, pet food incident, China has drawn up detection of melamine in animal feed of national standards, and the Sanlu milk powder incident, our country has not been detected in milk powder of melamine-related targets and standards. According to the side of the Tianjin Science and Technology Co., Ltd. detection of melamine in animal feed standards compiled in the detection of melamine in the formula will be used in laboratory supplies, including Standard, reagents, the column, such as pre-treatment products.
GCMS detection methods:
Melamine (Melamine), also known as melamine, cyanide-three urine. Formula C3H6N6, molecular weight 126.15, colorless crystal to white, non-combustible. A small amount of soluble in water, ethylene glycol, glycerin and pyridine, and micro-soluble in ethanol, insoluble in ether, benzene, carbon tetrachloride. Density (16 ℃ time) 1.573 g/cm3, melting point of 354 ℃. Combustion or heat, decomposition of hydride generation with cyanide, ammonia and nitrogen oxides, and other toxic and irritating smoke.
Melamine three homologue, respectively Cyanuric (cyanuric acid), one-Cyanuric (ammelide) and Cyanuric-II (ammeline). Experiments have shown that melamine and melamine homologue (Cyanuric, Cyanuric one-and two-Cyanuric) has the same toxic effect, and as complex melamine (MCs) for the overall drug Assessment of Science.
