Liquid-state NMR probes (Voxalytic)
High-sensitivity and high-resolution probes for liquid-state NMR spectroscopy
NMR SERVICE collaborates with Voxalytic on customised probes and is a world-wide sales representative for Voxalytic products. The portfolio includes ready-to-deliver probes for standard liquid-state NMR and specialised applications including reaction monitoring and screening, battery research, and chirality. Furthermore, we offer customisation options for NMR probes and detectors tailored to specific requirements.
Electrochemistry probe
In-situ experiments of charging and dis-charging cycles of cell-bag sized batteries are the main application of Voxalytic's electrochemistry probe. It is compatible to narrow- and wide-bore magnets.
Specifications:
- Double channel: 1H/19F and X (7Li, 23Na, etc.)
- RF efficiency: > 8 kHz/√W
- Z-gradient: 20 G/cm/A
- External frequency lock sensor
- 3 ports for electrochemistry
Compatibility:
- Plastic bag cell batteries
- All vendors
- Narrow, wide bore and special, e.g., 60 mm
- 300 MHz to 1.2 GHz
Features:
- Temperature control
- B1-enhancement due to Lenz-lens (LL) effect
- Digital tuning and matching
Options:
- Flow cell with µ-electrodes (coming)
- Triple resonance (coming)
- 3-axis gradient (coming)
- Wide tuning ranges down to 183 W
Flow probe
Applications like reaction monitoring, quality control, and many more benefit from a continuous sample flow which can not be covered with NMR test tube based probes. Voxalytic's flow probe provides fluidic ports easily accessible at the probe base and allows for interfacing reactors or other fluidic setups. The probe internal flow cell offers a microliter sized detection volume together with a high filling factor. If sample plugs are used, a flow detection sensor synchronizes the NMR acquisition with the sample plug delivery at the NMR detector.
Specifications:
- Double channel: 1H/19F and X (13C, 31P, etc.)
- RF efficiency: > 8 kHz/√W
- Z-gradient: 30 G/cm/A
- Active detection volume: 1 to 18 µL
- External frequency lock sensor
Compatibility:
- All vendors
- Narrow, wide bore and special, e.g., 60 mm
- 300 MHz to 1.2 GHz
Features:
- Integrated flow detection system
- Fluidic ports at probe base or top
- Temperature control
- Digital tuning and matching
Options:
- Optical flow cell for optical excitation (photo-CIDNP, photo-chemical reactions)
- Triple resonance (coming)
- 3-axis gradient (coming)
- Wide tuning ranges down to 183 W
High-throughput probe
The parallelization of the sample throughput of flow probes leads to a time and cost reduction of the NMR measurement as more samples can be analyzed per unit time. Voxalytic's high-throughput probe is unique on the market and variable in its degree of parallelization.
Up to 4 double resonant NMR detectors equipped each with its own Z-gradient, on-chip shim system and fluidic system can be used to perform 4 individual NMR simultaneously in a wide bore superconducting magnet. For narrow bore magnets 2 NMR detectors can be installed in one probe to parallelize workflows.

- 300 MHz to 1.2 GHz
Features:
- Integrated on-chip shim system
- Integrated flow detection system
- Fluidic ports at probe base or top
- Temperature control
- Digital tuning and matching
Options:
- Custom NMR detector arrangement
