A channel assembly is disclosed, which may comprise a microfluidic channel. Methods of manufacture are also disclosed as are detectors and detector components which may comprise such a channel assembly. An example is a detection apparatus comprising: a detector for detecting a substance of interest; and a pneumatic system comprising a microfluidic channel assembly comprising a first microfluidic channel for dispensing vapour to the detector, wherein the first microfluidic channel comprises a groove in a surface of a polymer body and a wall of the first channel is provided by a film bonded to the surface of the body over the groove.

A micro-reactor for a reforming process has a cold side and a hot side opposite the cold side. Inlets are defined in the cold side, the inlets configured for receiving reagents. An outlet is defined in the cold side, the outlet configured for exiting reforming products. A reforming chamber is in the hot side, the reforming chamber having a catalyst, the reforming chamber configured for reforming the reagents into the reforming products, the reforming chamber including channels extending toward an end surface on the hot side of the reforming chamber, and a return plenum. A reagent path is from the inlets to the reforming chamber, the reagent path configured to feed the plurality of channels with reagents. A reforming product path is from the reforming chamber to the outlet, the reforming product path configured to receive products from the return plenum.

A Liquid, comprising an hydrophobic flavonoid derivative electrochemically non-active, that is capable of restoring its electrochemical activity, the concentration of the flavonoid derivative being 10 ppm by weight or less, and an organic substance in an amount of 90% by weight or more.

The disclosure concerns methods comprising forming a phenol and acetone mixture from decomposition of a cumene hydroperoxide or a phenol, acetone, and AMS from the decomposition of a mixture containing dicumyl peroxide in a system comprising one or more reactors where at least a portion of an inner surface of the one or more reactors has a polymer coating and wherein the coating inhibits build-up of a fouling precipitate on the coated inner surface of the one or more reactors as compared to such build-up in the absence of the coating.

An apparatus includes a substrate having a recess and a multitude of particles arranged in the recess. A first portion of the particles is joined to a porous structure by means of a coating. A second portion of the particles is not joined by means of the coating. The first portion of the particles is arranged closer to an opening of the recess than the second portion of the particles so that a leaking of the second portion of the particles from the recess through the opening is prevented.

The present invention provides a system for evaporating a radioactive fluid, a method for the synthesis of a radiolabelled compound including this system, and a cassette for the synthesis of a radiolabelled compound comprising this system. The present invention provides advantages over known methods for evaporation of a radioactive fluid as it reduces drastically the amount of radioactive gaseous chemicals that are released in the hot cell. It is gentler and more secure compared to the known process and provides access to radiosyntheic processes that may not been acceptable for safety reasons related to release of volatile radioactive gases during evaporation. In addition, the process yields are higher because the radioactive volatiles are labelled intermediate species.
