Rapid, automated, component-specific particle characterization in a single, integrated platform

Morphologi 4-ID delivers detailed component-specific morphological descriptions of particulate blends through Morphologically-Directed Raman Spectroscopy (MDRS).  This combines automated particle imaging with Raman spectroscopy in a single, integrated platform, providing the power to unlock complex particle characterization problems.

  • Patented MDRS capability delivers representative component-specific particle size and shape data, delivering full characterization of your sample
  • All the functionality of the Morphologi 4 combined with a dedicated Raman platform for both physical and chemical particle characterization in a single, automated measurement
  • Automatically measures Raman spectra for hundreds or thousands of particles, saving valuable analyst time
  • Intuitive software ensures suitability for experienced and non-experienced spectroscopists alike
  • Easy correlation of morphological properties with chemical information provides the most comprehensive understanding of your sample
  • 21 CFR Part 11 software option ensures regulatory compliance
  • Adaptable workflows enable methods to be tailored to specific user or application requirements. Select particles for chemical analysis:

- manually, from particle images

- morphologically-directed, based on user-specified classifications (MDRS)

- automatically and objectively by the software

  • Ability to export spectra in industry-standard format supports unknown component identification using 3rd party spectral libraries
  • Tight control of laser power and acquisition time enables measurement optimization for a wide range of materials, from weak Raman scatterers to those that are thermally sensitive
