The detectable and measurable elements vary based on the material type (ferrous, stainless steel, aluminum, etc.) and the concentrations. PGNAA is able to detect a wide range of elements, and we are able to report the critical elements needed in each recycled metal type.
The accuracy is determined by the application, mainly the material and range of elemental concentration. Needless to say, using scientific means to determine the chemistry is markedly better than the educated guessing known as visual inspection.
Our proprietary analyzer doesn't use XRF and is also not surfaced oriented.
The term stands for Prompt Gamma Neutron Activation Analysis. If you are interested in how it works, check out this article.
The analyzer does not have limits on the production rate. On-line PGNAA is installed in applications ranging from less than 10 to more than 2000 TPH.
Our analyzers are real-time, so the analysis you get is for now and not yesterday. Yesterday isn't helpful!
