environmental background

with the continuous rapid growth of china's economy and the continuous improvement of per capita income, the scale of china's jewelry testing market continues to grow. at present, the consumption of many jewelry categories in my country ranks in the forefront of the world.

jewelry is expensive, and it is difficult to distinguish the authenticity with the naked eye. for consumers, jewellery companies and asset appraisal agencies, it is very important to ensure that they are genuine at a fair price. traditional analysis is to send jewelry to a professional testing laboratory for identification, which is time-consuming and expensive.

response plan

in order to solve the difficult and hot issues in gem identification, some new methods and technologies have been continuously introduced into the field of gemological research, providing a strong scientific guarantee for the objectivity, accuracy, and quantification of gem identification, which has greatly promoted the improvement of gem identification technology and research level. raman spectroscopy technology, as a micro-area non-destructive analysis technology, is favored by gemological research and gem identification fields. it is widely used in the detection of inclusion components and genetic types in gems, identification of artificially processed gems, identification of similar gems and jade varieties, and diamond identification and so on.

in response to market demand, suzhou langsheng scientific instruments co., ltd. has launched an intelligent handheld spatial optical raman spectrometer—ra200, which uses spatial coupling optics, electronic design, software technology, and fusion of scientific chemometric algorithms it has the characteristics of simple operation, excellent performance, convenient maintenance, and strong environmental practicability. it can effectively analyze the composition and processing technology of jewelry, distinguish true and false and good from bad. it is suitable for consumers, jewelry companies, pawn shops and asset appraisal agencies. provide integrated solutions for non-destructive and rapid testing of jewelry.

product advantages
