20220091010 · 2022-03-24 ·

A method for detecting concentration of organic particles (14), in particular viruses, with a determined target diameter in air (10) comprises organic and/or inorganic aerosol particles. Aerosol particles contained in the air (10) are bound in a fluid (40), so that said aerosol particles are contained as particles in the fluid (40). The fluid (40) with particles is exposed in measurement chamber (30) to a second light (B) fragmenting the organic particles and/or to an ultrasound (C) fragmenting the organic particles in the fluid (40). Before fragmentation of organic particles, a first light scattering of a first light (A) and after the fragmenting of organic particles, a second light scattering of the first light (A) on the fluid (40) are determined. Using difference between the first light scattering and the second light scatterings, the concentration of the organic particles (14) in the fluid (40) and thus in the air is determined.

Laser microdissection method and laser microdissection systems

A method for performing a laser microdissection for cutting a dissectate from a specimen using a laser includes the step of providing the specimen in a light path of an illumination system. The specimen is illuminated by the illumination system. A detector detects light emanating from the specimen. The light detected by the detector is analyzed. It is determined, based on the analysis of the light detected by the detector, whether a receptacle for collecting the dissectate is disposed in a predetermined collection position, at which the dissectate is to be collected in the receptacle after it is cut from the specimen. Laser cutting of the dissectate from the specimen is initiated based on it having been determined that the receptacle is in the predetermined collection position.
