After the launch of food pesticide residues rapid screening solutions, such as haicoptoelectronics and launched food, fish and veterinary drug residue rapid screening solutions, to protect the safety of your tongue.
Enoxacin, ciprofloxacin these names may not be familiar to you, but they are through food to your tongue, esophagus, intestines and stomach, harm your health..
Enoxacin is designated by the state as a special drug for animals. It is a yellowish powder with bitter taste, insoluble in water and soluble in organic solvents. It has wide antibacterial spectrum and special effect on mycoplasma. Ciprofloxacin is a slightly yellow crystalline powder, bitter taste, almost insoluble in water, soluble in acetic acid, slightly soluble in ethanol and trichloromethane. Enoxacin and ciprofloxacin are quinolones, and their structural formulas are as follows:
Enoxacin has a significant inhibitory effect on streptococcus, staphylococcus, escherichia coli and bacillus subtilis. It is usually used to treat infectious diseases such as mastitis in livestock, and is also added to feed and drinking water as a preventive medicine for diseases. Ciprofloxacin inhibits staphylococci, pneumococci, and streptococci and is commonly injected into animals as a therapeutic agent or added to their drinking water as a disease-preventing agent.
In China, the maximum residue limit (MRL) of enoxacin and ciprofloxacin in animal-derived foods is stipulated as follows (ciprofloxacin is the main metabolite of enoxacin in animals, so the determination of both as markers in animal food is the sum of the two contents)
Excessive residues of these drugs in animal food will cause harm to consumers' health. For example, excessive accumulation of enoxacin and ciprofloxacin in human body can lead to highly allergic reactions, gastrointestinal discomfort, central nervous system abnormalities and other symptoms, and lead to the formation of drug-resistant bacteria, affecting the clinical efficacy of these drugs.
At present, the common detection methods mainly include microbial method, liquid chromatography, high performance liquid chromatography, high performance capillary electrophoresis, liquid chromatography-mass spectrometry, immunoassay and immunoaffinity chromatography, etc. These detection methods generally have high cost and long detection cycle, which cannot meet the requirements of rapid field detection. Therefore, it is necessary to establish a rapid detection method for this kind of drugs
.For this phenomenon, for example, haioptoelectricity, based on spectral analysis technology, combined with surface enhancement reagent, launched a rapid screening solution for fish and veterinary drugs, and the whole detection process can be completed within 15 minutes. The method is simple and fast, and can detect many kinds of veterinary drugs.
Box Raman spectrometer rfs1000-t and handheld Raman spectrometer RFS1000 are based on laser Raman fingerprint spectral analysis technology and network data verification technology, combined with quinolone antibiotics rapid detection reagent and pretreatment equipment, which can quickly realize the rapid detection of food safety. It is specially designed for law enforcement and quick screen detection, easy to use and simple to operate.

In addition to food, fish and veterinary drug residue detection, such as haicaodian also developed pesticide residue and other as many as hundreds of common subjects rapid detection program, committed to analysis and research, service and sharing, for the health food safety industry escort!
