Nuclear Magnetic Resonance Spectrometer

MacroMR12-150V-I / MacroMR12-150V-TAS Developed by Niumag Analytical, MacroMR12-150V-I and MacroMR12-150V-TAS are newly launched large-bore vertical NMR systems. These instruments are designed to operate under multi-field coupling conditions—including temperature, pressure, and fluid flow—while also accounting for the effects of natural gravitational forces, making them highly applicable to geotechnical and subsurface research.The system features a C-shaped, large-aperture, semi-open magnet, allowing for easy sample placement and convenient integration with auxiliary components. It integrates both major NMR capabilities: relaxation analysis and magnetic resonance imaging, and is equipped with Niumag’s 4th-generation digital spectrometer for enhanced performance. With a clean industrial design and simplified user interface, the system offers a faster, smarter, and more intuitive user experience.
