The invention relates to a method and a series of devices for dry cleaning, activating, modifying, coating, and biologically decontaminating (degerming, disinfecting, sterilizing) surfaces by means of an atmospheric pressure plasma generated using a surface barrier discharge.
Device (1) for determining a pressure, a temperature and / or a particle density of a gas or gas mixture (G), comprising • a laser device (3) which is set up to emit a laser beam (5), • a measuring unit (40), which is set up to measure absorption values of a gas or gas mixture (G), the laser device (3) and the measuring unit (40) being arranged in such a way that the laser beam (5) can traverse at least part of the gas or gas mixture (G) and can be directed to the measuring unit (40) so that the absorption values of the gas or gas mixture (G) can be measured by means of the measuring unit (
The invention relates to a process of treating objects, particularly of cleaning and decontaminating or disinfecting or sterilizing objects. A plasma processed gas (PPG) is provided, and by contacting this plasma processed gas (PPG) with a liquid, a sterilizing gas and a sterilizing liquid are generated. The objects to be treated are contacted with the sterilizing liquid in a first treatment step and with a treatment gas in a second treatment step, wherein the treatment gas can be the sterilizing gas or the plasma processed gas (PPG).
The present invention relates to a device for plasma-treating hollow bodies, such as bottles, vials, syringes, shut-off caps, etc., in particular with a view to sterilising said hollow bodies, and is equally suitable for various discharge types such as dielectric barrier discharge and discharges with high frequency and microwave excitation.
The invention relates to a method and to a device for quickly decontaminating and sterilizing preferably thermolabile goods using a plasma gas that is preferably generated from air as a process gas, with the subsequent humidification of said plasma gas with water.
The present invention relates to an apparatus for igniting and generating a propagating, diffuse microwave plasma. The device is suitable for generating microwave plasmas for the purpose of plasma treatment of surfaces and substances, in particular of three-dimensional objects as well as of particles under atmospheric pressure.
The solutions according to the invention are presented in the claims.
The present invention relates to a device as well as a system and a method for treating an object, in particular one or more free-form objects, with plasma. The object to be treated can in particular be a raw food such as an egg, fruit or vegetable, or packaging as well, or respectively a cap, etc. Treating the object with plasma preferably serves the object of decontaminating and sterilizing the surface of the object.
The invention relates to a method for the biological decontamination of material to be treated (4) by means of a reactive gas (R) comprising the generation of a reactive gas (R) from a process gas by igniting a plasma, filling a container (3) with the reactive gas (R) and the Decontamination of the material to be treated (4) in the container (3) by means of the reactive gas (R).
