Detecting small metallic contaminants in food via magnetization
A practical metallic-contaminant detecting system using three high-Tc RF superconducting quantum interference devices (SQUIDs)
31-Jul-2015 -
The detection of metallic contaminants in foods is important for our health and safety. However, existing inspection methods have limitations. For instance, the X-ray radiation method cannot detect contaminants with sizes smaller than 1 mm with current practical X-ray levels, and it cannot be ...
