High Resolution Raman Spectrometers - LabRAM HR 800

Technical characteristics:

The HR800 produced by HORIBA JOBIN YVON is an integrated Raman system, high stability bench-top for reproducible Raman measurements at high, medium or even low spectral resolution. The microscope is coupled confocally to a 800 mm focal length spectrograph equipped with two switcheable gratings.

  • High spectral resolution (0.3 cm-1/pixelat 633 nm);
  • Large spectral range of Raman shift from  30 to 4000 cm-1 ideal for organic and inorganic species;
  • Unique adjustable angle notch filter technology;
  • LabSpec Software for control the instrument, data acquisition, data manipulation and mapping option;

Description

LabRAM HR 800 Raman Spectrometer  is a powerful optical technique for materials study and characterization based on  inelastic scattering of light due to light-matter interaction during which the energy of the incident laser will be shifted. This energy loss is characteristic for a particular bond in the molecule. The Raman spectrum  provide qualitative and quantitavie information: peak position is determined by chemical species;  line intensity is proportional to concentration; shift in position of the peak indicate the stress and temperature effect and the width the structural disorder.

**********************

Applications:

LabRAM HR 800 Raman Spectrometer  can be used  for the analysis of solids, liquids and solutions for:

  • chemical identification, characterization of molecular structures;
  •  to determine the composition and phase (crystalline/amorphous) of composites materials;
  • environmental stress on a sample and  crystal quality and composition of alloy semiconductors;
  •  nature of oxides on compound semiconductors;
  •  polymers characterizations and polimer nanocomposites;
  • chemical and biological detection using SERS technique;
  • micro/nano structures characterization ( micro/nanorods,  carbon nanotubes), self assembled molecule (SAM) on functionalized substrate and other.
