Raman spectroscope is a versatile and simple analytical technique for identifying the bonding structure of samples and determining their composition. Using this instrument an unknown substance whether inorganic or organic can be identified by getting its Raman spectra within normal operating range of the microscope and comparing the position of its peaks against a catalog of Raman spectra of known elements and compounds. The instrument does not need any specific sample preparation or generation of any vacuum / inert atmosphere inside of the sample compartment. By using microscope one can mark the desired location / phases of the sample and direct the laser to fall at the selected point. The instrument equipped with software collects Raman spectra and selected part can be identified by comparing the spectra available in inbuilt library.
