Abstract
The present invention concerns the preparation of solutions, particularly for implementing analytical methods, in particular by spectrometry, particularly for producing standard solutions which are useful, for example, for calibrating spectrometers or for implementing diagnostic methods. It allows the implementation of an easy process for preparing such standard solutions.
Claims21
A process for preparing an aqueous solution of at least ten different products to be dissolved, wherein the process comprises dissolving in the solvent of the aqueous solution one or more soluble beads, the one or more soluble beads having a surface, wherein the at least ten products to be dissolved are present at the surface of each of the one or more soluble beads and being grafted thereon, wherein the beads are calibrated with a homogeneous diameter ranging from 1 to 4 mm.
A set of soluble beads carrying at least ten different products to be analysed grafted onto the surface of each of the soluble beads, wherein the beads each have a predetermined amount of the at least ten different products grafted onto their substantially equal surface.
A process for preparing soluble beads carrying at least ten different products to be analysed grafted onto the surface of each of the soluble beads, comprising a first step of impregnating polymer beads with a solution containing the at least one product of the ten products to be dissolved in order to allow the grafting of said products of the beads, then a step of drying the grafted beads obtained, wherein the beads are calibrated with a homogeneous diameter and the amount of product grafted onto each bead is predetermine, from 1 picogram to 100 micrograms per bead.
