VARNMR is used to study the water status in a wide variety of (bio)porous materials, for example intact plants, plant components (i.e. fruits, seeds, leaves, roots), soils, and foods.
This NMR spectrometer is dedicated for in vivo NMR spectroscopy, metabolic studies of living organisms, solid state NMR, and magic-angle-spinning NMR. The system has been extended with an 10 T/m gradient set for diffusion ordered spectroscopy (DOSY) and q-space imaging. The latter is used to quantify (bio)porous structures and food systems.
The LF-MRI is based on an electromagnet system with a 10 cm air gap, equipped with an 1 T/m flat gradients set for optimal accessibility. This system is used for anatomical and functional imaging of plants, fruits, seeds and other living organisms, food systems, (bio)reactors and porous materials. A Rheo-accessory is available for Rheo-MRI.
Multi-dimensional NMR spectroscopy for high resolution molecular structure elucidation.
The 3T-MRI is equipped with different gradient insert systems for gradients up to 1 T/m, for in vivo study of intact plants under well-controlled environmental conditions in a mini-phytotron, as well as small-scale (bio)reactors, (bio)catalysis systems, porous media (e.g. soils, rocks), low water/low mobility food systems; both fluid, solid and gas phase can be detected. The vertical bore of 3T-MRI makes this system specially suited for the study of plants, small trees and (bio)reactors.
This system is used for analytical NMR, multi-dimensional NMR spectroscopy for molecular structure elucidation, and non-targeted screening of bio-fluids.
CW-ESR uses free radicals as an external probe to study for example various aspects of longevity in seeds. These measurements can be combined with (MAS)NMR and MRI studies to study e.g. lipid oxidation, redox state by spin label reduction, membrane phase characteristics.
