Raman Spectrometer

Raman spectrum indicates the vibration and rotation information of the substance molecules. Different materials have different characteristic of spectrum from other materials--characteristic peak, which provides fingerprint spectrum for the substance characterization and identification. CNI launched Raman Spectrometer with the features of compact design, high resolution, high sensitivity, simple measurement and operation, can replace the old spectrophotometer and widely used in chemical and biological research, environmental science, jewelry appraisal, forensic appraisal, food/drug safety inspection, geological exploration and many other fields.
