The PRX system is based on the Reflective Phantom Interface (RPI) technology, designed and patented by ProXentia, which exploits the properties of light reflected from surfaces with very low reflectivity. The PRX sensor is made using a material that, in contact with aqueous solutions, becomes almost completely transparent. The very little reflected light carries information on the molecules that are near the surface.

The surface of the PRX sensor is coated, in some small areas (“spots”), with receptors able to capture the molecules to be analyzed (for example mycotoxins) that could be present inside the sample. On the surface, there are multiple spots with various receptors that capture different types of molecules. The way these spots reflect light provides a direct measurement of the concentration of contaminants in the sample, all of them analyzed simultaneously.


The technology owned by ProXentia allows to design and develop multiparametric cartridges. Unlike the other methods currently on the market, the PRX system can detect up to 10 contaminants during a single analysis, providing a quantitative measurement of concentration for each of them. This way, with a single test lasting a few minutes, it will be possible to carry out fast and complete analyses to verify the quality and safety of different products.

Complex Matrices

The PRX system allows to easily analyze different types of matrices. The RPI technology operates without being influenced by the optic complexity of the sample. Therefore, in our cartridges it’s possible to analyze colored and turbid samples, or even samples containing particulate matter, without the need of complicated extraction methods and thus simplifying the analysis procedure.

Fast & Easy to use

The proprietary RPI technology allows to significantly simplify both the procedures of extraction and analysis. In fact, it’s possible to design easy and customized sample preparation protocols, reducing the use of reagents. Also, ProXentia developed a fast and very simple analysis procedure. Few easy steps are required, thus reducing the need of the operator’s actions and lowering the chances of mistakes.
