NMR. Modelo: 100PRO

Modelo: 100PRO. NMR is a spectroscopic characterization technique in which a sample of interest is placed into an external, static magnetic field (B0) and pulsed with an oscillating magnetic field (B1) at a specified angular frequency (w) that is dependent on an isotope’s gyromagnetic ratio (γ). This is known as the Larmor Frequency.  w = γB0 The principal difference between the Nanalysis low-field benchtop NMR spectrometers and the higher field superconducting magnets is the method used to generate the static magnetic field. Instead of generating a magnetic field using a cryogenically cooled superconducting solenoid, the 60 and 100 MHz benchtop NMR uses carefully engineered permanent rare-earth magnets. In some respects, operation of Nanalysis’ benchtop NMR is similar to cryomagnet-based systems. For example, samples are typically prepared in standard 5 mm NMR tubes to a total sample volume of 0.5 to 0.7 mL in a deuterated solvent (section 3.1). Acquisition of NMR is performed with onboard software, with a highly automated, simplified NMR acquisition interface designed to reduce the complexity of system operation. This interface provides the option for manipulation of basic acquisition parameters prior to data collection and spectral processing during the spectral work-up (section 4). These simple manipulations will be easily recognized by experienced users and easy for new users to learn and adopt.
