The mq -ProFiler is a compact and portable TD-NMR analyzer that does not have any sample size restriction. It is specifically designed for industrial process/research and quality control. The instrument is fitted with a one-sided magnet and RF probes that can perform 1H-NMR experiments on the surface as well as near-surface volume elements of arbitrarily large samples.
Part of the award-winning mq-series, the mq-ProFiler has been employed in various applications for both R&D and QC.
Supported by Bruker’s unparalleled hardware and electronics design, this single-sided, ready-to-use TD-NMR instrument provides reliable data for research and QC/QA. The mq-ProFiler requires only minimal set-up and is controlled via PC through a flexible, intuitive, and easy-to-use software interface.

TD-NMR: The Method of Choice
The mq-ProFiler NMR analyzer uses nuclear magnetic resonance methods, which are similar in principle to the high-resolution MRI and NMR, and predicts chemical and physical properties of materials by analyzing the data in time-domain.
The method is fully non-invasive, and does not require any solvent or sample preparation. The TD-NMR signal is unaffected by opacity, color or surface characteristics. The hydrogen nuclei present in a small volume of sample produces signal, which is obtained in few seconds to minutes.
The calibration procedure is both simple and short. After calibrating a system, recalibration is not required unless the hardware is altered.
Design Advantages
- Mechanical stability: Robust construction necessary for use in production or industrial environment
- Sample-independent tuning: Insensitive to the dielectric properties of the sample, which means tuning and matching are not needed following sample loading
- Negligible artifacts: Efficient probe design eliminates the background 1H signal and acoustic ringing, leading to very short dead time and enabling the visibility of sample components having fast relaxation properties
- Variable measurement depths: Hot-swappable probes for probing various depths
- Short powerful pulses: Enables short high-powered pulses, leading to excellent signal-to-noise ratio in the presence of inhomogeneous magnetization field of single-sided magnet
In-package food analysis.
mq-ProFiler: Software Advantage
The mq-ProFiler software provides push-button, easy-to-use routine analysis. It is easy to set up new calibrations and the mq-ProFiler software guides the user through this operation. The mq-Profiler has pulse sequences that are adapted to inhomogeneous magnetic field, while the software enables users to manage measurement parameters and offers endless possibilities to implement novel pulse sequences. Also available are sophisticated data processing routines like ILT or NNLS fitting.
