To incorporate a compound into the pores of a microporous or mesoporous material (30), obtained by a sol-gel process, it is contained within a transparent quartz chamber for vaporizing or sublimation at a temperature of at least 30degreesC and preferably at least 50degreesC up to 200degreesC. The compound is vaporized in a vacuum chamber (11), in the apparatus (10), and the porous material is frozen at a temperature at most-40degreesC before it is placed under a vacuum. For vaporizing, the chamber containing the compound and the porous material is heated by immersion in a heated oil bath, while the porous material is separated from the container base (13) by thermal insulation (14). The compound is a marker or a liquid coupled to a marker, a fluorophore, luminophore or a chromophore. |
