Dynamic Particle Image Analysis System
Reliable Particle Detection System
The system utilizes a microcell and advanced optics to accurately and efficiently detect particles. Using normal lenses, the apparent size of particles can be affected by the depth of the particle relative to the lens. The iSpect DIA-10 uses a telecentric lens that maintains a constant image magnification. This means that no matter where the particle is located in the field of vision, the system will accurately determine the size of the particle. The autofocus function increases the imaging efficiency*1 which makes it possible to accurately detect foreign objects and obtain repeatable number concentration.
*1: The ratio of the number of sample particle images acquired to the number of particles in the sample that has flowed through the system.
Efficient Image Acquisition
The microcell increases image acquisition efficiency by passing particles through a narrow imaging area, which optimizes the number of particles observed. Compared with a conventional cell and lens, the microcell clearly shows particle images and fewer particles pass outside of the lateral imaging area. This makes it possible to reliably detect particles and obtain highly repeatable number concentration (Coefficient of Variation (CV) ±5 %*2).
*2: When measured using a Shimadzu standard sample. Depends on the sample.
