Abstract

The invention discloses a method for detecting melamine in foods or feeds by using an ion mobility spectrometry (IMS) technology, which comprises the following steps: preparing a sample of foods or feeds to be detected; exerting the sample to be detected on a sampling paper, then leading the sample to be detected to a detection inlet of an ion mobility spectrometer; obtaining an ion mobility spectrogram of the sample to be detected; matching the characteristic peak and arrival time of the sample to be detected on the ion mobility spectrogram with the characteristic peak and arrival time in a standard material library so as to determine whether melamine is in the sample to be detected.

Description

technical field [0001] The invention relates to a method for detecting melamine by using an ion mobility spectrometry (IMS) technique, which is particularly suitable for testing melamine contained in food or feed. Background technique [0002] Melamine is referred to as triamine for short, and its scientific name is triaminotriazine, and it is also known as melamine, cyanuramide, and trimeramide. Melamine is a widely used organic chemical intermediate with a uniform structure, and its main use is as a raw material for the production of melamine-formaldehyde resin. German chemist Liebig first synthesized melamine in 1834, which is a by-product of the urea production process. [0003] In earlier toxicology studies, melamine was considered mildly toxic. In the rat experiment, the median lethal dose of melamine is 3 g / kg. The test shows that after feeding large doses of melamine to rats, rabbits and dogs, no obvious poisoning phenomenon is observed; Cause reproductive and uri...
