In addition to physical characteristics such as particle size and shape, the chemical identity of particulates can be important for a number of applications such as;

  • Component specific particle characterization for particle mixtures e.g. inhaled pharmaceutical medicines.
  • Identification of contaminant or outlier particles in production samples.
  • Forensic investigation of unknown particulate samples.

Malvern Instruments have developed advanced instrumentation for the chemical identification of particulate samples combining the high resolution size and shape information from automated imaging with the high chemical specificity of Raman spectroscopy.
