The invention relates to a gas sensor having a mechanical microresonator, which has an excitation apparatus for optically exciting a mechanical oscillation of the microresonator as well as a reading apparatus for detecting the oscillation of the microresonator, wherein the reading apparatus comprises a waveguide which is implemented together with the microresonator on a dielectric or semiconducting substrate and is intended to optically read the oscillation of the microresonator, and wherein the excitation apparatus has an optical waveguide which is implemented on the same substrate and optically connects an excitation light source to the immediate surroundings of the microresonator. The invention also relates to a use of such a sensor to analyse a gas composition.

Photoacoustic gas sensor and its use

Method and device for inactivating a microbiologically contaminated mass containing solid particles. The method includes mixing the mass containing solid particles with a gelatinizing agent, transporting the mixed mass of solid particles and gelatinizing agent through a shaping device structured so that the mixed mass, at least in one area, is shaped to form a lamellar volume with a layer thickness of between 1 mm and 3 mm, and impinging the formed lamellar volume of the mixed mass with accelerated electrons.
