Extending the capability of conventional NMR instruments
Key features
-
Well-established scientific background and proven technology
-
Operates as add-on with any conventional NMR spectrometer and gradient-capable probe; requires no additional hardware or software
-
Advanced sample cell and RF filter system
-
Straightforward embedding of voltage pulses in conventional NMR pulse programs, ready-made pulse programs
-
Probe and user protection system
Selected applications
-
Physical chemistry – ion pairing and association in simple and complex (polyelectrolytes) ionic mixtures.
-
Batteries and fuel cells - chemically selective measurement of ionic migration.
-
Biochemistry – biomolecular charge and association.
-
Analytical chemistry – electrophoretic analysis of complex ionic mixtures
-
Pharmaceutical chemistry – release and association of charged drugs
-
Metallorganic chemistry – the structure of supramolecular complexes from the observed charge
