“Everyone in the company loves it,” Scoggins said. “By analyzing shape as well as size, the Morphologi G3 adds another dimension to the usefulness of particle characterization data. It is good for R&D. It helps us more fully understand the materials we are working with and what we can do with them. Having previously contracted out much of our particle characterization work, we now benefit from shortened R&D times and much richer data. We can run more samples and it is easier and quicker to interpret data generated in house.”
Commenting on the practicalities of using the Morphologi G3, he went on to say, “The system is automated, intuitive to use, and requires little sample preparation. Since most of our materials are dry dispersions, we like the integrated sample dispersion unit. In fact, we’ve bought an extra chamber so that one sample is being prepared while another is running. Essentially, we can all get on with other things while the measurements are taking place.”
The R&D team has also carried out some wet work. In one study of a wet granulation, granulation time and the amount of granulation solution sprayed were studied relative to granule growth. “Being able to look at the continuum in terms not only of granule size, but also of shape was a useful exercise in determining granule growth,” said Scoggins.
For the future, this team also plans to use the Morphologi G3’s facility for characterizing foreign particles collected on a filter.
The Morphologi G3 from Malvern Instruments combines microscopy and image analysis to measure the size, shape, and intensity of particles from 0.5 to 10000 µm. It captures and stores images of every particle examined. Powerful software means that with just a few clicks of the mouse, data is transformed into useful information, allowing users to make decisions quickly and with confidence.
