Features

NMR is an extremely powerful analytical method. In combination with the affordability of the AvanceCore, this makes NMR the ideal tool to address a large range of analytical questions, including structure elucidation and verification, molecular interactions, and quantitation. The AvanceCore solution offers NMR at a price similar to a standard liquid chromatography mass spec instrument.

Benefits

NMR offers many advantages over other analytical techniques. The AvanceCore provides better value for money than other methods:

With NMR, what you see is what is present. Chromatographic analysis requires process steps such as liquid injection or sample evaporation. Potential sample degradation or unwanted reactions complicate the assignment of signals.
NMR selectively detects nuclei such as ¹H, ¹³C, ¹⁹F and ³¹P which are present in organic molecules. This is not apparent with other analytical techniques. For example, UV detectors for chromatography miss many substances without a chromophore. IR and mass detectors have similar limitations.
With NMR, substances can be identified and quantified against any reference standard. Other analytical methods rely on a reference standard of the same material.
1D NMR experiments can be run with standard parameters for most samples. Several compounds are identified and quantified from a single spectrum. HPLC, for instance, can also deliver good separation and signal-to-noise — provided that the method was optimized for the particular application. NMR helps you to save time and money.

Applications

Linear Prediction

Learn how Linear Prediction (LNP) on AvanceCore™ NMR systems enhances spectral resolution and signal‑to‑noise without increasing experiment time. This AppNote demonstrates how LNP suppresses truncation artefacts and enables reliable detection of weak signals and dilute impurities - ideal for efficient 1D and 2D NMR analysis in modern analytical workflows.

Direct Assignment of the Carbon Backbone with Room Temperature Probes at Medium Fields: The INAD NMR experiment

The INADEQUATE NMR experiment facilitates the direct structural assignment of organic molecules via the carbon backbone. This poses advantages over other, indirect methods. Learn how to record the experiment at 400 MHz with a room temperature probe in 24h - even with a limited amount of sample substance.

Decoupling: The Key to High Resolution and Sensitivity in
One-Dimensional NMR Spectra

Two important factors in one-dimensional NMR spectroscopy are high resolution and sensitivity. Both can be more than doubled when using heteronuclear decoupling, which allows for the separation of overlapping signals as demonstrated for the analysis of diluted components in reaction mixtures.

Mixture Analysis with NMR: Benefiting from Multi-Signal Suppression

¹H NMR spectroscopy is great for detecting impurities and trace compounds. There is no “hiding” as most organic molecules contain the highly sensitive ¹H nucleus! Lift the lid to discover what selectively suppressing large signals can uncover.

Radiation Damping: What It Is and What To Do

One of the strengths of NMR spectroscopy over other methods is that the sample amount can be chosen relatively freely, from the sub-milligram-range to several grams. Provided that radiation damping is correctly accounted for, measurements of trace compounds, undiluted products, and the mixture of both can be performed very straightforwardly.

Determining Relaxation with the Inversion-Recovery Experiment

NMR experiments typically consist of RF pulses followed by a period of recording the resulting NMR signal. Very often, several such sequences are executed after another - for instance to increase the signal to noise ratio by averaging. It is important to wait with the application of a new pulse until the RF signal from the previous pulse has decayed.

The AvanceCore is highly cost effective and facilitates uncompromized performance in high-resolution NMR. Outstanding dispersion and signal-to-noise ratio enable mixture analysis down to ppm concentrations. The AvanceCore supports state-of-the-art 2D NMR methods to elucidate molecular structure at the atomic level.

Identification and quantitation: The above 1H spectrum was acquired with the AvanceCore Foundation from a 20 mg sample in less than 5 minutes. The sample contains 100 ppm (0.002 mg) of the following impurities: acetonitrile, acetone, ethyl acetate and acetic acid in DMSO-d6.

The AvanceCore Foundation also supports state-of-the-art 1H-1H 2D experiments such as TOCSY, COSY, ROESY and NOESY. The above spectrum shows TOCSY-correlations of the anti-inflammatory drug Ibuprofen.The TOCSY can be used for structure assignment.

With the AvanceCore Foundation, the 1H DOSY NMR experiment for mixture analysis can be performed. DOSY is often referred to as “chromatographic NMR”. Just like LC-MS, it resolves the different mass and diffusion properties of indivual mixture components.

The AvanceCore Select supports heteronuclear experiments (HSQC, HMBC...) which are essential for molecular structure elucidation. The above spectrum shows a 2D 1H/13C HSQC-TOCSY experiment recorded from a 20 mg Ibuprofen sample.

Configurations

In order to keep costs low, Bruker has streamlined the AvanceCore into three pre-configured packages.

Foundation: In the most fundamental version, the AvanceCore provides high-resolution ¹H NMR spectroscopy. The bundle includes a 400 MHz NMR magnet, a console and a 5 mm probe.

Select: The AvanceCore Select includes all the hardware and software for ¹H and heteronuclear (¹³C, ³¹P...) state-of-the-art experiments.

Convenience: The AvanceCore Convenience includes a 24-position sample changer. The IconNMR software enables open access use and automated routine measurements.

Your instrument can grow with your needs: An existing AvanceCore can easily be upgraded from Foundation to Select and from Select to Convenience.
