Raman spectrometer

The handheld Raman spectrometer adopts a high-performance research level Raman system, which simplifies and professionalizes the functions of the spectrometer. Based on mobile phones, it can achieve cloud network end-to-end Raman monitoring and information retrieval of the Internet of Things. The new generation of handheld Raman spectrometers have the characteristics of ultra-high sensitivity and high optical resolution, and are widely used in multiple fields and industries such as medicine, medical care, public safety, chemical testing, food safety, and jewelry testing.

Product Introduction:

It can quickly and accurately detect illegal additives, chemical additives and adulterated substances in daily food. The instrument is based on laser Raman fingerprint spectroscopy analysis technology and network data verification technology, combined with enhanced reagents and pre-treatment equipment, and can quickly detect food safety in a few minutes. It is specially designed for on-site law enforcement and rapid screening detection, easy to use and simple to operate. Combined with enhanced reagents and pre-treatment equipment, it can quickly detect food safety in a few minutes.

Food safety is regarded as a global problem that concerns the national economy and people's livelihood. In recent years, food safety problems such as melamine, Sudan red, clenbuterol and gutter oil have occurred frequently, seriously affecting the development of my country's food industry. Conventional laboratory food safety testing methods cannot meet the needs of on-site rapid testing due to their small number, high cost and long testing cycle. The development of fast and accurate illegal additive detection technology has become a current hot research direction. As a fast, non-destructive and safe detection technology, Raman spectroscopy has the characteristics of fast and correct, good reproducibility, simple sample pretreatment, compact and portable, and wide application. Combined with special surface Raman enhancement reagents and simple sample pretreatment equipment, it can simply, accurately and efficiently detect illegal/abused additives, pesticide/veterinary drug residues, adulterated harmful substances, toxic chemicals and other items in food.

Testing items:

Pesticide residues (thiabendazole, carbendazim, diquat, difenoconazole, methyl thiophanate, etc.), veterinary drug residues (malachite green and its metabolites, crystal violet, enrofloxacin, ciprofloxacin, oxolinic acid, furazolidone, etc.), additives (sodium thiocyanate, benzoic acid, sorbic acid, caffeine, etc.), melamine, sibutramine, sildenafil and more than 200 kinds of residue and additive detection items, and customized projects can be customized according to customer needs.
