Patent ID: 8518343

Claim:
A method for the production of a solution from at least one solid matter in a solvent, the solvent being supplied to a single cavity from a reservoir via a single microchannel, the method comprising: storing the at least one solid matter, soluble in the solvent, in the single cavity in a solid state by receiving the at least one solid matter through the single microchannel or the single cavity; introducing a medium in the single cavity, wherein the medium is paraffm that is insoluble in the solvent, and wherein the medium covers or encloses the at least one solid matter so that dissolution of the solid matter which is soluble in the solvent is prevented; rinsing the single cavity by allowing a rinsing agent to flow through the single microchannel; supplying the solvent, through the single microchannel, to the single cavity in which the at least one solid matter is stored; and treating the medium, which is insoluble in the solvent, in such a way that contact between the solvent and the soluble solid matter, and consequently dissolving of the solid matter, which is in the solid state, in the solvent, occurs and the solution is produced.
