Microtrac offers image analysis, 3D image analysis, and on-line image analysis capability.
The characterization of particulate systems, once dominated strictly by size analysis, is evolving. Particle morphology, as measured by dynamic image analysis (DIA), provides detailed information regarding the physical properties of materials. The key properties of particulate systems and the products manufactured from them can change with no significant difference in the LD size distribution reported. Image analysis can rapidly identify problems and significantly reduce troubleshooting time.
Particles in a flowing stream, backlit by a high speed strobe light, are photographed by a high resolution digital camera to create a video file of images for the flowing particles. The pixel size of the camera and the number of pixels in the image are used to measure a large number of particle size and shape parameters, along with a measure of transparency.
Microtrac’s DIA measurement principle involves sample that is introduced through a nozzle for dry dispersion and analysis or suspended in a circulating fluid for wet analysis. As particles enter the sensing zone, the high speed camera will take photos and transfer the information to a PC. Microtrac’s sophisticated software delivers over 30 size and shape parameters to the user.
Some of the parameters of importance to customers include length, width, aspect ratios (W/L), sphericity, transparency, solidity, and surface roughness, among many others.
Although the measurement technology of DIA is straightforward, the data analysis used to identify and solve problems is extremely powerful.
