Description

Raman spectroscopy is the "fingerprint spectrum" of molecular vibration. Different material molecules have different vibration frequencies, so they are often used as an important basis for material identification. Raman technology has many unique advantages over traditional infrared and chemical methods. First, Raman scattering of water is very weak, so Raman spectroscopy is an ideal tool for studying biological samples and chemical compounds in aqueous solution. Second, Raman's peaks are sharp and clear, and are more suitable for quantitative research, database search, and qualitative analysis using differential analysis. Third, Raman can cover about 4000 wavenumber intervals at the same time, and can analyze organic matter and inorganic matter. If the infrared technology covers the same Intervals must change gratings, beam splitters, filters, and detectors. Fourth, samples (solid, liquid, gas) for Raman measurements no need to be pretreated, and with advantages of no contact, lossless, real-time and testing materials through transparent packaging. The BRS-785 series Raman spectrometers are equipped with a narrow linewidth low power laser with an excitation wavelength of 785 nm. The spectral range is up to 3600 cm-1 and the spectral resolution is up to 8 cm-1. According to the intensity of the Raman spectrum, different sensitivity specifications can be selected, which are BRS-785-01 universal type and BRS-785-02 high sensitive type. The instrument is stable in performance, easy to carry, and supports OEM customization and secondary development, providing a great convenience for laboratory and on-site Raman detection.
