Ram-Ar-2015
This is a fiber-optic-coupled device (with diode array detector and a laser as light source) which capable of providing fast and simultaneous collection of Raman spectra.

   The benefits of array technology include very fast scanning
   with ability to scan all wavelengths range of in less than 1
   second, which can be used for
fast chemical reactions and
   denaturing materials.
   The benefits of array technology include very fast scanning
   with ability to scan all wavelengths range of 150-4500 cm-1
   in less than 1
second, which can be used for fast chemical          
   reactions and  denaturing materials.
   Traditional spectrometers use stepper motors to select      
   the required wavelength, while with array technology each
   wavelength is selected by electrical scanning which results
   in excellent wavelength reproducibility.

   of providing fast and simultaneous collection of  Raman        
   spectra.

Applications:

Due to its sensitivity, high information content and non-destructive nature, Raman is now used in many applications across the field of chemistry, biology, geology, pharmacology, forensics, pharmaceuticals, materials science, and failure analysis.

In addition to providing unique information about a sample, Raman offers several additional benefits, including:

-         Minimal or no sample preparation

-         Sampling directly through glass containers

-        Non-destructive analysis, so the same sample can be used in other analyses

-        Non- intrusive analysis, permitting study of more labile sample features, such as crystal structure

-        Minimal water interference

-         No interference from atmospheric CO2 or H2O
