Abstract: The interior of a fractionating tool for fractionating dioxins is packed with a purification layer and an adsorption layer. The adsorption layer includes a first adsorption layer including an activated carbon-containing silica gel layer and a graphite-containing silica gel layer, and a second adsorption layer including an alumina layer. When a solution of dioxins is injected into the purification layer and is supplied with an aliphatic hydrocarbon solvent, the solvent dissolves dioxins in the solution of dioxins and passes through the purification layer and the adsorption layer. In this process, non-ortho PCBs, PCDDs and PCDFs among dioxins are adsorbed to the first adsorption layer, and mono-ortho PCBs among dioxins are adsorbed to the second adsorption layer. As a result, dioxins are fractionated into a group including non-ortho PCBs, PCDDs and PCDFs, and mono-ortho PCBs.

Abstract: Example minimalist magnetic resonance imaging (MRI) radio frequency (RF) coils that are connected to off coil circuitry by capacitive coupling plates are described. A min-imalist MRI RF coil may have some elements that form a traditional coil located off the coil in off coil circuitry. An MR procedure may involve a number of minimalist MRI RF coils that are moved through an excitation zone as a patient is moved through the excitation zone. Example minimalist MRI RF coils may be selectively connected to off coil circuitry while the coils are in the excitation zone. The coupling may be made by capacitive coupling plates. Unlike conventional systems, example systems have capacitive coupling plates with properties that facilitate maintaining a constant capacitance between a coupling plate associated with the coil and coupling plates associated with the off coil circuitry as the coupling plates move relative to each other.
