The company Pamas Particle Measuring and Analysis Systems presents an image analysis system that is suitable for liquids such as emulsions and dark liquids that cause problems when analyzed with automatic particle counters. The FastPatch 2 GO microscope analyzes the entire filtration surface of a membrane filter in accordance with ISO 4407. An automatic image analysis system analyzes particles on filter surfaces and provides information on the length and width of each individual particle. The user can record images of each relevant particle and of the entire surface of the membrane filter and add these to the analysis report together with the size information of each particle displayed. In addition, the analysis report contains an overview of the entire filtration area analyzed; the overview shows the selected particles and their respective location on the membrane filter. The measurement results are output in accordance with the cleanliness class standards SAE AS 4059 F, NAS 1638, ISO 4406 and ISO 16232. In addition, the integrated polarization filter makes it possible to detect transparent sample components such as gelatinous particles.
