Combining a 400 MHz superconducting magnet, distributed architecture, and intelligent automation, it addresses the needs of research labs and industrial facilities across diverse fields.
Core Components & Technology
1. 9.39 Tesla Superconducting Magnet
The heart of the CAN400 is its high-homogeneous, ultra-shielded 400 MHz superconducting magnet, generating a 9.39 Tesla magnetic field. With a 54 mm standard bore, it accommodates various probes while maintaining radial/vertical 5 Gauss lines at 0.6 m/1.0 m for safety. Key features include long liquid helium hold time, an intelligent level gauge with low-helium alarms, and a control screen for real-time status monitoring—ensuring stable, high-quality signal acquisition.
Distributed Console with High-Precision Control
The console adopts an advanced distributed architecture, defaulting to 2 RF transceiver channels (expandable to 8) for scalable performance. It delivers exceptional precision: 4 ns timing resolution, 0.0005 Hz frequency resolution, and 0.001° phase resolution, with simultaneous setting of frequency, amplitude, and phase. High-speed data acquisition (16-bit resolution, 250 MS/s sampling rate) and ±12.5 MHz receiver spectral width support complex experiments. Software-controlled power-up/down enhances user convenience.
3. Multi-Nucleus Probe & Auto-Tuning
The probe supports 5 mm sample tubes and detects multiple nuclei (¹H, ¹³C, ¹⁵N, ³¹P, ¹⁹F, etc.), including rare isotopes like ¹⁰⁹Ag. It features deuterium lock for stability, 50 G/cm maximum Z-gradient strength, and rapid automatic tuning/matching. ¹H/¹⁹F decoupling experiments, it ensures high sensitivity and resolution across wide temperature ranges.
4. Intelligent Software & Automation
Running on Windows, the software enables 1D/2D NMR experiments, pulse sequence editing (graphical interface), and universal data format export. Remote access allows real-time monitoring and control, while the 72-slot auto sample changer (installed at the magnet waist) uses bidirectional rotation and a quick pre-sample device for second-level sample switching—boosting throughput for high-volume studies.
