The accurate and periodic control of the chemical composition of raw materials used in a production process is of paramount importance in guaranteeing the stability of the quality of the finished product. With its state-of-the-art analytical equipment, Stazione Sperimentale del Vetro is capable of accurately and reliably determining both the concentration of the main components of the raw materials, and their content of trace contaminants.

When the quantification of impurities or trace contaminants is required, the determination is carried out by “wet chemistry” techniques, using instruments such as GF-AAS, ICP-OES or ICP-MS, depending on the specific element to be analyzed and to the limit of detection or quantification to be achieved. Detection limits of the order of 0.1, or even 0.01 ppb for some elements, can be achieved for example using ICP-MS.
