NMR Observe Probes

Optimized for X-nuclei detection

: BBFO broadband probe

The inner coil of these versatile probes is tunable over a frequency range that enables observation of nuclei between ³¹P and ¹⁵N, depending on probe configuration as well as ¹⁹F on BBFO models. The outer coil is optimized for ¹H decoupling and observation. You can, for example, acquire ¹³C spectra with ¹H decoupling, then switch to ³¹P observation with ¹H decoupling. Further, you can change observed nuclei using an automated tuning and matching device (ATM).

BBFO Broadband Probes

The inner coil of these versatile probes is tuneable over a frequency range that enables observation of ¹⁹F as well nuclei between ³¹P and ¹⁵N. The outer coil is optimized for ¹H decoupling and observation. You can, for example, acquire ¹³C spectra with ¹H decoupling, then switch to 31P or ¹⁹F observation with ¹H decoupling. Any of these nuclei can be fully automatically selected and optimally tuned and matched (ATM).

Standard Broadband Probes are available as

Type	Frequency	Diameter	Gradients
BBFO	300 MHz - 600 MHz	5 mm	Z-Gradient
SmartProbe	400 MHz - 600 MHz	5 mm	Z-Gradient
BBO	300 MHz - 600 MHz	10mm	Z-Gradient

Dual Probes

Dual Probes allow you to switch observation between two nuclei: The inner coil is optimized for nuclei A (e.g. ¹³C), whilst the nucleus of the outer coil is optimized for nucleus B (usually ¹H). Bruker Dual (DUL) Probes offer an ideal combination of outstanding sensitivity, lineshape, and pulse widths. These probes are often used with samplechangers to automate routine spectroscopy. For example, with a ¹³C / ¹H DUL Probe you can obtain ¹³C and ¹H NMR from a large collection of samples overnight or all weekend long.

DUL plus Probes

DULplus probes are characterized by their very high ¹H and ¹³C sensitivity. The superior gradient design allows very short gradient recovery times. Any method for single or multiple solvent suppression using presaturation or pulsed field gradients are applicable. This feature, which is unique for X-observe probes, even enables studies of samples in protonated solvents such as samples from reaction control, biological samples and body fluids.

Standard DUAL Probes are available as

Type	Frequency	Diameter	Gradients
DUL	300 MHz	5 mm	Z-Gradient
DUL	400 MHz	5 mm	Z-Gradient
DULplus	400 MHz	5 mm	Z-Gradient
DUL	500 MHz	5 mm	Z-Gradient
DUL	600 MHz	5 mm	Z-Gradient

Selective Observe Probes (non standard)

When the highest sensitivity is required, Bruker’s Selective Probes are optimized for the nucleus of interest and provide unsurpassed sensitivity, the best lineshape and resolution. They can be used for natural products, metabolites or specialized NMR research focusing on one nucleus. Need an observe nucleus or a size not listed?
