• High-precision Time-Domain NMR (TD-NMR) analyzer operating at a frequency of 60 MHz (1.41 T magnetic field)
• Fast, non-destructive, and non-invasive analysis
• Relaxation times: T₁ relaxation (spin-lattice), T₂ relaxation (spin-spin), and free induction decay (FID)
• MRI contrast agent development and magnetic relaxometry: screening and evaluation of magnetic relaxation properties
• Pulse/signal generation: high-precision pulse programming with 20 ns time resolution
• Digital quadrature receiver, 14-bit A/D converter, up to 12.5 MHz sampling rate
• Virtually unlimited pulse and echo sequences
• Sample volume: approximately 0.5–2 ml in tubes (Ø 7.5–18 mm)
• Temperature control: 20–60 °C
• Control and operation via minispec software
• Characterization of aqueous nanoparticle dispersions—especially superparamagnetic iron oxide nanoparticles (SPIONs)

• Excitation of particle magnetization by a high-frequency sinusoidal magnetic field (25.699 kHz, 20 mT/μ₀)
• Detection and evaluation of higher harmonics (starting from the 3rd order) up to approximately 2 MHz for detailed analysis of magnetization dynamics
• Magnetic fingerprint analysis for assessing contrast agent suitability, particle quality, and dispersion behavior
• Software control and data evaluation via a custom-developed Julia-based platform (Prof. Dr. Tobias Knopp)
• Real-time Fourier transformation, harmonic analysis, and automated data processing
• Sample volume: 40 μL SPION dispersion (e.g., 15 mmol Fe/L) in a 200 μL Eppendorf tube
• Typical applications: magnetic particle imaging (MPI), relaxometry, particle design, and stability analysis
