Liquid Flow Imaging (LFI): beyond laser diffraction

The Liquid Flow Imaging (LFI) dispersion unit upgrades the Litesizer DIF into a combined laser diffraction and Dynamic Image Analysis (DIA) system. Pairing rapid size distribution with detailed shape data and outlier detection enables analysis beyond spherical particle assumptions. This is illustrated on examples of microcapsules, cocoa powder, and cement.

Instruments that combine laser diffraction and image analysis represent a powerful advancement in particle characterization technology. By integrating two complementary techniques into a single platform, these systems provide both rapid particle size distribution data and detailed information about particle shape and morphology. Laser diffraction offers high-speed, statistically robust measurements across a wide size range, also into the nanometer range, while image analysis adds visual confirmation and shape descriptors that help identify outliers, irregular particles, agglomerates, and other critical features. 

This combination enables a more complete understanding of particle systems, supporting better quality control, formulation design, and process optimization across industries such as pharmaceuticals, chemicals, mining, cement, food processing and materials science.
