Automated imaging - Advanced particle characterization INTRODUCTION Automated imaging provides high resolution direct measurement of the size, shape and other properties of particles from below one micron up to several millimeters in size. It is often used in conjunction with other particle characterization techniques, to gain a deeper understanding of the sample or to crossvalidate particle sizing methods. Malvern Instruments has a range of automated imaging instrumentation which can be used to solve particle characterization problems such as: • Measurement of shape differences where...

WHAT IS AUTOMATED IMAGING? Automated imaging techniques use a digital camera to capture 2D images of a dispersed particulate sample. Individual particle images are identified using digital thresholding techniques, and then analyzed to determine their particle size, particle shape and other physical properties such as transparency. Statistically representative distributions can be constructed by automatically analysing tens to hundreds of thousands of particles per measurement providing valuable information on the sample as whole. The measurement process is automated through electronic...

Automated imaging - Advanced particle characterization PARTICLE SHAPE, WHEN SIZE ALONE ISN’T ENOUGH For many applications, a particle size distribution provides adequate information about the sample. However, for some applications particle shape can provide more appropriate or complementary information. There are three main categories where this is relevant. Single particles or agglomerates? Many particle sizing methods require complete dispersion of any agglomerates in the sample in order to make an appropriate measurement. Being able to view individual images in the dispersion and analyze...

Automated imaging - Advanced particle characterization CHOOSING THE RIGHT AUTOMATED IMAGING SOLUTION When choosing the most appropriate automated imaging solution for your needs, there are a number of questions to consider: What types of material do I need to measure? Where will the instrument be used? Will my needs change in the future? Will I only measure samples as a wet dispersion or do I need the flexibility to measure dry powders as well? Will it be used in central R&D as a shared resource where there are many users and different types of samples might be measured? Will different...

Automated imaging - Advanced particle characterization Introduce sample Keeping particles in focus The Sysmex FPIA-3000’s unique sheath flow mechanism keeps all the particles flowing through the measurement cell in a very precisely defined flow path. This ensures that even the smallest particles in the sample stay at the focal plane of the measuring optics, delivering unrivalled image quality for particles below 10μm in size. An added benefit of the sheath flow is that it prevents particles from the sample touching the optical windows, substantially reducing particle wear and window...

Easy, reproducible sample dispersion High quality measurements Powerful yet intuitive software Appropriate dispersion of the individual particles and agglomerates within a sample is critical to achieving meaningful results. Good spatial separation and representative sampling of the particles is required. An integrated dry powder disperser option makes preparing dry powder samples simple and reproducible. A precise amount of sample is dispersed automatically using a unique compressed air dispersion mechanism controlled from within the software for reproducible dispersions every time. A range...
