Application of Material Identification

Rainbow-Light material identification technology for materials, textiles and plastics.
Rainbow-Light material identification technology for materials, textiles and plastics.

Rainbow-Light has a team devoted to the development of spectral analysis and application for more than 10 years of experience. Recently, we expanded into different fields of materials identification through the infrared spectroscopy identification technology. We accepted commissions from the industries, academics, research units to customize the relevant materials identification equipment. Since our inception, we always adhere to resolve problems by innovation and continue to pursuit of excellence.

Our world has a wonderful phenomenon. That is, all the different substances on the light response will not be the same, so in the visible world we see a variety of different colors of the material. All the more so, different color materials on the invisible light response are more different. Therefore, using spectrum analyze materials、 substances、 elements、 compounds… etc., is a very practical technology.

Spectral qualitative analysis is mainly to identify and identify what elements of material composition. Spectral quantitative analysis is the measurement of the content of the relevant components in the material. Qualitative analysis is to compare the IR spectra of each substance, quantitative analysis through the Beier-law (Beer-Lambert) to calculate the amount of how much.

Rainbow-Light material identification technology is the use of spectral qualitative, quantitative analysis technology, with an exclusive spectral fingerprint identification technology, more accurate identification of all kinds of materials for plastic materials identification, textile material identification, a variety of polymer materials, composite materials Identification and identification of various materials authenticity.
