Raman Spectrometer NRS-200
Raman Spectrometer NRS-200 is high throughput analytical instrument that helps in quick and reliable identification of a variety of liquid, solid, or powder samples depending on their unique chemical fingerprint. It employs non-destructive technique and analyses by illuminating a sample with monochromatic light which is measured by determining the light scattered by a sample using a spectrometer. It is a versatile tool that is used by many academic and research institutes.
