Fast Field Cycling NMR Relaxometry
Further Beyond Conventional NMR

About us

Stelar is unique in offering carefully crafted, highly-specialized Fast Field Cycling Nuclear Magnetic Resonance (FFC NMR) relaxometry analytical research tools, which can be configured to meet the needs of the user. Since 1984, Stelar instruments are used for research and industrial applications around the globe.

FFC NMR relaxometry is a unique, non-invasive analytical technique giving a snapshot of the physical motions and interactions within a substance/material. FFC can be used to show physical changes/differences both qualitatively and quantitatively through simple fingerprinting or by defining motion coefficients such as for diffusion or rotation.

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.

Fast field cycling NMR relaxometry performed either by Spinmaster or Smartracer revealed its powerfulness in agro-food and environmental chemistry.
