Magritek Spinsolve Benchtop NMR Spectrometer

Overview

The Magritek Spinsolve is a high-performance, compact benchtop nuclear magnetic resonance (NMR) spectrometer engineered for routine and research-grade molecular analysis in standard laboratory environments. Unlike conventional superconducting NMR systems requiring cryogenic liquid helium and nitrogen, the Spinsolve utilizes a permanent magnet operating at 60 MHz (for ¹H), delivering robust, stable, and maintenance-free operation without refrigerants or dedicated infrastructure. Its measurement principle is based on pulsed Fourier-transform NMR spectroscopy, enabling quantitative, non-destructive, and matrix-insensitive detection of nuclei including ¹H, ¹⁹F, ¹³C, and ³¹P. The system’s inherent chemical specificity supports structural elucidation, reaction monitoring, and compositional quantification—without reliance on external calibration standards in many cases. Designed for accessibility, it delivers high signal-to-noise ratio (SNR), narrow baseline linewidths (< 1 Hz typical for ¹H in CDCl₃), and excellent spectral reproducibility over extended acquisition periods—enabling unattended overnight experiments.

Key Features

• 60 MHz ¹H operating frequency with field homogeneity actively stabilized via real-time shimming algorithms
• Multi-nuclear capability supporting ¹H, ¹⁹F, ¹³C, and ³¹P detection with pre-tuned broadband probe options
• Integrated pulse sequence library including 1D (standard, inversion recovery, DEPT), 2D (HSQC, HMQC, HETCOR, COSY, JRES), and quantitative (qNMR) methods
• Compact footprint (70 × 50 × 40 cm) and low power consumption (< 300 W), compatible with standard 110–240 V AC outlets
• Self-contained, closed-cycle temperature control (20–60 °C) for reaction monitoring and thermal stability studies
• Automated sample handling option available for up to 16 samples per run, supporting high-throughput QC workflows
• Robust mechanical design with vibration-damping chassis and passive magnetic shielding, minimizing environmental interference

Sample Compatibility & Compliance

The Spinsolve accepts standard 5 mm NMR tubes (including Wilmad and Bruker-compatible variants) and supports both solution-phase and semi-solid samples. It complies with international safety standards IEC 61010-1 (electrical safety) and IEC 61326-1 (EMC for laboratory equipment). While not certified for clinical use, its architecture aligns with GLP and GMP-aligned quality systems—particularly when deployed in pharmaceutical QC labs where audit trails, user access controls, and electronic signatures are implemented via optional software modules. Data integrity meets ALCOA+ principles, and raw FID files are stored in vendor-neutral formats (e.g., JCAMP-DX, NMRPipe-compatible) to ensure long-term archival and third-party processing compatibility. The system supports ISO/IEC 17025-compliant validation protocols, including linearity, precision, and limit-of-detection assessments for qNMR applications.

Software & Data Management

SpinsolveControl™ software provides an intuitive, workflow-driven interface built on Qt/C++ with native support for Windows and Linux. All acquisitions, processing, and reporting are performed within a single environment featuring real-time preview, automated phasing/baseline correction, peak integration, and customizable report generation (PDF, CSV, PNG). The software includes full audit trail functionality compliant with FDA 21 CFR Part 11 requirements—including electronic signatures, user role management (admin/operator/analyst), and immutable record logging. Raw time-domain data (FID) and processed spectra are stored in hierarchical project folders with embedded metadata (operator, timestamp, pulse sequence, solvent, temperature). Integration with LIMS and ELN platforms is supported via RESTful API and standardized file export protocols. Optional ChemDraw and MestReNova plug-ins enable direct structure-based prediction and spectral simulation.

Applications

• Teaching & Training: Enables hands-on NMR instruction without infrastructure overhead; ideal for undergraduate chemistry labs and graduate-level spectroscopy courses
• Synthetic Chemistry: Rapid verification of product identity, purity assessment, and impurity profiling directly from crude reaction mixtures
• In Situ Reaction Monitoring: Real-time tracking of kinetic profiles using flow cells or temperature-controlled batch probes
• Quality Control/QA: Quantitative determination of active pharmaceutical ingredients (APIs), excipients, and residual solvents per USP and Ph. Eur. 2.2.17 guidelines
• Materials Science: Polymer tacticity analysis, crosslink density estimation, and small-molecule characterization in battery electrolytes or catalyst formulations
• Food & Agriculture: Authenticity testing (e.g., olive oil adulteration), fatty acid profile quantification, and metabolite screening

FAQ

Does the Spinsolve require cryogens or external cooling?

No. It uses a permanent magnet and solid-state shim system—zero liquid helium or nitrogen is needed.
Can it be used for regulatory submissions?

Yes—when configured with 21 CFR Part 11-compliant software and operated under documented SOPs, data are admissible for ICH Q2(R2) method validation and regulatory filings.
What sample volume is required?

Standard analysis uses 500–600 µL in a 5 mm tube; low-volume kits support down to 150 µL with minimal SNR penalty.
Is remote operation supported?

Yes—via secure VPN or institutional network; full instrument control, acquisition, and processing are possible from off-site locations.
How often does the system require recalibration?

The magnet and RF electronics are factory-calibrated for life; routine performance verification uses internal reference standards (e.g., 0.1% ethylbenzene in CDCl₃) per ASTM E2830-12 guidelines.
