Method for analyzing a particle accumulation on a membrane, device for automated analysis and sample preparation unit therefor

摘要

In order to analyze a collection of particles (3; 5; 6; 7) on a membrane (1) with an optical microscope (100; 200; 303a) a parallel determination of contrasting particles (3; 5; 6; 7) for a and to enable the same membrane (1), it is proposed that the permeability of the membrane (1) for light radiation is increased before the particle accumulation is analyzed.
