The present invention relates to a mixing apparatus for introducing and distributing a liquid additive into a gas flow, in particular for an exhaust gas system of an internal combustion engine. The mixing apparatus comprises a gas-guiding section for guiding the gas flow and a metering-in device for introducing the additive into a metering-in region of the gas-guiding section. Furthermore, a heating device for actively heating at least one heating section of the gas-guiding section is provided. The heating section is arranged in the metering-in region and/or downstream of the metering-in region. The gas-guiding section has, in the heating section, at least one elevated portion projecting radially into the gas flow for influencing the flow of the gas flow and thus the preparation of the additive.

A vaporizer device may include a vaporizer body configured to couple with at least one vaporizer cartridge including a first reservoir and a second reservoir.

The application relates to microfluidic apparatus and methods of use thereof. Provided in one example is a microfluidic device comprising: a first fluidic input and a second fluidic input; and a fluidic intersection channel to receive fluid from the first fluidic input and the second fluidic input, wherein the fluidic intersection channel opens into a first mixing chamber on an upper region of a first side of the first mixing chamber, wherein the first mixing chamber has a length, a width, and a depth, wherein the depth is greater than about 1.5 times a depth of the fluidic intersection channel; an outlet channel on an upper region of a second side of the first mixing chamber, wherein the outlet channel has a depth that is less than the depth of the first mixing chamber, and wherein an opening of the outlet channel is offset along a width of the second side of the first mixing chamber relative to the fluidic intersection.

In a method of detecting a test substance, a test substance is detected using a sample analysis cartridge supplied with a sample. The sample analysis cartridge includes: a passage part having a gas-phase space; and liquid containers communicating with the passage part through openings. The liquid containers include: a first liquid container containing a first liquid containing magnetic particles; and a second liquid container containing a second liquid containing a labeled substance. The magnetic particles are sequentially transported to the liquid containers through the gas-phase space in the passage part. Thus, the magnetic particles carry a complex of the test substance and the labeled substance. The test substance is detected based on the labeled substance in the complex.

The invention describes a method for the synthesis of compounds comprising the steps of: (a) compartmentalising two or more sets of primary compounds into microcapsules; such that a proportion of the microcapsules contains two or more compounds; and (b) forming secondary compounds in the microcapsules by chemical reactions between primary compounds from different sets; wherein one or both of steps (a) and (b) is performed under microfluidic control; preferably electronic microfluidic control, The invention further allows for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, and which is co-compartmentalised into the microcapsules.

An apparatus (2) for dissolving a gas into a liquid includes a liquid inlet (4) for supplying liquid into the apparatus, a gas inlet (6) for supplying gas into the liquid within the apparatus and a venturi (52) arranged to dissolve the gas into the liquid passing through the venturi.
