Medium-Sized NMR Imaging Analyzer NMI20-060 Series

NMI20-060H-I and NMI20-060V-I Series NMR Imaging Analyzers integrate relaxation analysis with magnetic resonance imaging to accommodate testing needs for samples of varying sizes. They have already been widely applied in food research.The NMI20 series NMR instruments are built with rare-earth permanent magnets, ensuring zero maintenance costs. No chemical pretreatment is required before testing, making the process simple and efficient. The system is particularly advantageous for qualitative and quantitative analysis of water and oil content, as well as their binding states.
