Product Description
The Nuclear Magnetic Resonance (NMR) Spectroscopy System is a state-of-the-art analytical instrument designed for detailed molecular structure determination, quantitative analysis, and advanced research applications. Widely used in chemistry, pharmaceuticals, biotechnology, materials science, and academic laboratories, NMR spectroscopy provides precise information about molecular composition, atomic connectivity, and dynamic behavior.
Built with high-field superconducting magnet technology and advanced digital signal processing, this NMR system delivers high sensitivity, exceptional spectral resolution, and reliable reproducibility. It is engineered for both routine analytical workflows and complex structural investigations.
Principle of Nuclear Magnetic Resonance
NMR spectroscopy is based on the magnetic properties of atomic nuclei that possess spin, such as hydrogen (¹H) and carbon (¹³C). When placed in a strong magnetic field, these nuclei align with the external field. Upon exposure to radiofrequency (RF) pulses in the radiofrequency region of the electromagnetic spectrum, the nuclei absorb energy and transition between spin states.
As they return to equilibrium, they emit signals detected by the receiver coil. These signals are processed using Fourier Transform (FT-NMR) to generate a spectrum. The resulting spectral data provide detailed information about:
Chemical shifts
Coupling constants
Molecular framework
Functional groups
Molecular symmetry
Purity and composition

Advanced 2D and 3D Capabilities
The system supports advanced multidimensional experiments including:
COSY (Correlation Spectroscopy)
HSQC (Heteronuclear Single Quantum Coherence)
HMBC (Heteronuclear Multiple Bond Correlation)
NOESY (Nuclear Overhauser Effect Spectroscopy)
These techniques allow researchers to analyze complex molecular systems with enhanced clarity.
