NMR Observe Probes

Optimized for X-nuclei detection

: BBFOplus broadband probe

The inner coil of these versatile probes is tuneable over a frequency range that enables observation of nuclei between ¹⁹F resp. ³¹P and ¹⁵N, depending on probe configuration. 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).

BB(F)O 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).

BBFOplus Broadband Probes

BBFOplus broadband probes are designed for highest over all sensitivity and line shape. It facilitates observation/irradiation of all NMR nuclei in the range ³¹P to ¹⁵N in addition to ¹H and ¹⁹F. Any of these nuclei can be fully automatically selected and optimally tuned and matched (ATM). A further key feature which those probe offer is the ability to observe ¹⁹F with ¹H decoupling and to perform two-dimensional ¹H/¹⁹F spectroscopy with superior quality. As two separate coils are used for these two nuclei, artefacts common with double tuning of one coil are eliminated.
The high performance Z-gradient has been designed for highest linearity and shortest gradient recovery times. Combined with its excellent line shape this probe facilitates superior single or multiple solvent suppression using presaturation or pulsed field gradients as required for samples from reaction control, biological samples and body fluids.

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.

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?
