Note: In some of the pictures, two particles are seen in the same frame: The instrument is not able to differentiate between single particles and agglomerates. However, in cases where you are interested in agglomeration, you can sort the particles based on this the agglomerates might have a higher intensity or be elongated compared to single particles. Figure 3: Screen shot from Morpholygy G3 — pictures of individual particles in the powder mixture. These particles are mainly salt square particles and coffee creamer darker particles with uneven edges.

By analysing the particles by using different characteristics, for instance by sorting them by intensity, it is possible to separate salt from coffee creamer in the mixture, as clear differences in the intensity color is observed. When this first differentiation has been made, a filter based on intensity can be applied, and in the optimal case, the particle size distribution of only the coffee creamer in the mixture can be made. Thus, the analysis can be set up in order to analyse the particles with regard the specific properties that you are interested in.

If you are interested in only looking a fibers, analysis with regard to elongation might be optimal — if you are interested in looking a special properties with regard to shape, circularity might be the most relevant. The present example is just an example of the possibilities. However, it should be noted, that for complex mixtures, method development takes time as it requires training to set up the correct filters for your purpose. Especially for comparison of particle characteristics of different batches of the same material, this type of microscopy analysis is brilliant, as even small changes in morphological properties will be detected.

More information about these possibilities to be published soon. What would be relevant in your case? What is a polymorph? What is the size of a particle?

    Powder Sampling and Particle Size Determination : T. Allen :

    This technique measures the distribution of equilibrium velocities of particles settling through a liquid under the influence of gravity. Non-spherical particles are measured in terms of the diameter of a sphere of the same material that settles at the same velocity in the same suspension liquid. The SediGraph III directly measures mass by x-ray absorption and determines particle size by direct measurement of settling velocity.

    Direct measurements require no modeling.

    Particle Size Measurement

    Particles are suspended homogeneously in a carrier liquid. They pass through a thin flow cell in the optical path. Light is transmitted through the flow cell, thus projecting silhouettes of the particles onto a high-resolution camera sensor. The high frame rate and high resolution of the camera combined with a high-speed host computer enables the characterization of thousands of particles per second in real-time. This technique is ideal for applications where shape, not just diameter, is critical information for predicting raw material performance.

    The SentinelPro is a class-leading dynamic image analyzer that is ideal for applications where particle shape, not just the particle size, may be critical information for predicting raw material quality and to maintain a high level of process control.

    Particle morphology provides important information regarding the physical shape properties of your sample. It has been shown that shape can affect flowability, dispersion, packing density, segregation, aggregate formation, and microstructure character. The particle size, or fineness, of powdered materials can be determined by measuring the powder's air permeability. When a homogenized bed of powder with a known porosity and has its height changed in a test tube, its porosity also changes.
