The Morphologi G3-ID provides a unique capability, combining automated static imaging features of the Morphologi G3 with chemical identification of individual particles using Raman spectroscopy to enable the measurement of component specific particle size and particle shape distributions.

Overview

This fully automated instrument is designed to allow both particle characterization scientists with limited spectroscopy experience and more experienced spectroscopists to get an in-depth understanding of their particulate samples. Key features:

  • Measures particle size, shape and chemical identity in one platform.
  • Automates Morphologi G3 with Kaiser Optical Systems RamanRxn1 spectrometer.
  • Integrated dry powder dispersion with accurate dispersion energy control automates sample preparation for consistent measurements of both fragile and robust materials.
  • Simple SOP operation from sample dispersion through to size, shape and chemical analysis.
  • Automatic selection, targeting and chemical classification of 1000’s of individual particles.
  • Export function for third party forensic library investigations.
  • Single point manual targeting mode for manual selection of particles for chemical analysis.
  • Powerful and intuitive software interface making both visual and statistical interpretation of your data easier than ever.

How it works

The Morphologi G3-ID is ideally suited to solving complex particle characterization problems where component-specific particle size and shape distributions are required. This includes measurement of components within powder blends and suspensions, along with the identification of contaminant or suspicious particles within product formulations.

The measurement workflow can be divided into three distinct steps, each of which can be automated:

  • Sample preparation
    This step is critical to getting good results; spatial separation of individual particles and agglomerates is the goal. The Morphologi G3SE has an integrated dry powder disperser which makes preparing dry powder samples easy and reproducible. The applied dispersion energy can be precisely controlled, enabling the measurement process to be optimised for a range of material types. Dispersion is achieved without explosively shocking the particles, avoiding the damage of fragile particles while ensuring strongly agglomerated materials are dispersed. Effective dispersion of fibres can also be achieved.
  • Particle size and shape measurement
    The instrument automatically measures the size and shape of particles in a dispersed sample in exactly the same manner as the Morphologi G3. This ensures there is no compromise on the reliability of the particle size and shape data, which is not the case with many chemical mapping and imaging techniques.
  • Chemical identification
    The instrument automatically finds particles of interest for chemical identification based on pre-defined classification rules. A Raman spectrum is acquired from the center of mass of each particle. Chemical identification is then achieved based upon established spectroscopic algorithms incorporated within the Morphologi G3-ID software. This allows enumeration of defined classes of particles as well as the reporting of component specific particle size and shape distributions.
