Abstract: The invention relates to the use of microjet reactor for processing biomass. The cell lysis of flowable biomass is thereby carried out by means of multiple high-speed liquid jets which collide with one another, wherein the liquid jets contain the cells or consist wholly of the flowable cell mass, wherein intact or wholly or partially lysed biomass is added to at least one of the colliding high-speed liquid jets, and an extraction takes place simultaneously with the collision of the liquid jets or subsequently thereto. The lysis of the cells is initiated or facilitated by the forces that occur on acceleration, introduction of the acceleration, collision of the jets and mixing of the jet constituents.

Abstract: The invention relates to an apparatus and method for the production of dispersions and solids by way of controlled precipitation, co-precipitation and self-organization processes in a microjet reactor, a jet of solvent containing at least one target molecule and a jet of nonsolvent colliding with each other, at specified pressures and flow rates, at a collision point in the reactor chamber of the microjet reactor, and the microjet reactor having a gas inlet for introducing gas into the reactor chamber and an educt outlet for discharging the educts in a stream of gas. This results in very rapid precipitation, co-precipitation or a chemical reaction, during the course of which micro- or nanoparticles form.

Abstract: The invention relates to a method for producing microparticles or nanoparticles of water-soluble and water-insoluble substances by controlled precipitation, co-precipitation and self-organization processes in microjet reactors, a solvent, which contains at least one target molecule, and a nonsolvent being mixed as jets that collide with each other in a microjet reactor at defined pressures and flow rates and thereby effect very rapid precipitation, co-precipitation or a chemical reaction, during the course of which microparticles or nanoparticles are formed.

Abstract: The invention relates to a measuring instrument and method for detecting the content of oil, hydrocarbons and oxidizable gases in air or compressed air. In order to develop a measuring instrument for detecting the content of oil, hydrocarbons and oxidizable gases in air or compressed air, said instrument being suitable for detecting concentrations in the lower ?g/m3 range or in the ppb range and allowing measuring accuracy of 10 micrograms oil/m3 air at a measurement error in the single-digit percentage range, it is proposed according to the invention that the measuring instrument comprises an air or compressed-air connection and, connected thereto, a flow limiter to which a catalyst is connected that is connected in turn with a photoionization detector, switchable means being provided for routing the air or compressed air over the oxidation catalyst or past it directly to the photoionization detector.
