Fast Field Cycling NMR Relaxometry

Further Beyond Conventional NMR
Fast Field Cycling NMR Relaxometry

About Stelar

Stelar designs and manufactures advanced Fast Field Cycling (FFC) NMR relaxometers, powerful analytical instruments that reveal how molecules move and interact inside materials.

Since 1984, researchers and industries worldwide have relied on Stelar’s technology to explore physical and chemical properties in fields ranging from materials science to life sciences.

FFC NMR relaxometry is a non-invasive technique that provides a molecular fingerprint of a sample, allowing users to detect changes, compare materials, and quantify molecular motions such as diffusion or rotation.

HETERONUCLEI

FFC NMR relaxometry is mostly used for proton-based analyses (1H nucleus), as detailed in the other applications pages. It is however possible to study dispersion curves or simpler decay curves of T1 for other nuclei, such as deuterium (2H), fluorine (19F), lithium (7Li), compounds enriched in carbon-13 (13C) and more.

Driving Innovation Through Your Expertise

I have used the FFC nuclear magnetic relaxation dispersion (NMRD) extensively for probing the wettability of petroleum fluids embedded in carbonate rock cores and shale rocks. These works have proven […] a valuable tool for investigating in situ the molecular dynamics of petroleum fluids.

The Stelar SMARtracer FFC Relaxometer has allowed us to measure the relaxivity and NMRD profiles of many new paramagnetic species and has led to the publication of our work in higher impact journals.

Magnetic Relaxation Dispersion (MRD) provides a powerful means to explore molecular dynamics directly from the time range from picoseconds to milliseconds […] MRD opens the window to slow dynamics often difficult to study by other spectroscopic methods in heterogeneous materials.

Only after we had purchased a STELAR Spinmaster as our first commercial instrument of this sort, we reached the performance and the ease of use our students needed for demanding applications including polymers, porous media, and liquid crystals.

My group is fairly new to the FFCNMR game, but the learning curve has been made a lot gentler by the excellent technical support we’ve received from Stelar.

Stelar has served us well over the past 15 years by providing reliable field-cycling instruments that have opened up a wide range of new research possibilities.
