The cations present in the wine arise mainly from radical absorption but may increase due to accumulation / contamination during the various production phases, from pressing to bottling. 
Being able to identify a critical phase of the process is the basis of every company quality system in order to be able to constantly guarantee the quality of the product.

The determination is made via icp-oes. this technique interfaces an inductively coupled plasma source with an optical detector (photomultiplier). 
The principle of operation involves a flow of argon transporting the vaporised sample inside an icp torch, where it reaches a temperature of 6000-8000°c, and ionisation and atomisation take place. 
In an icp-oes (optical emission spectroscopy) the spectral composition of the light emitted by the source is analysed through a monochromator (diffraction reticle) that breaks the entering light into spectrums that are intercepted by a photomultiplier.
