Welcome to the Nuclear Magnetic Resonance (NMR) Facility at the Section of Technical Foundation, Malaysian Institute of Chemical and Bioengineering Technology, Universiti Kuala Lumpur (UniKL MICET). The NMR facility located at the Pilot Plant building, is equipped with one superconducting NMR spectrometers operating in liquid mode.

The goal of NMR facility, UniKL MICET is provide research support to undergraduate students, postgraduate students, academicians and researchers of the UniKL and other universities or institutes for advancement of their research.

Therefore, we offer services to both internal (UniKL) and external users. This equipment is operated hands-on by trained technical staffs. On site, Ph.D and technical staffs are ready to facilitate technical assistance and trainings.

The important characteristics of NMR spectroscopy which most favourable to the industries and research applications are some of the more common NMR active nuclei include 1H, 2H, 13C, 11B, 15N, 19F, 31P and 195Pt. In addition, only a small quantity of material is required for analysis such as sample sizes of 5-20 mg are generally sufficient for most NMR experiments and the sample preparation is simple and minimal. Typically, samples are simply dissolved in an appropriate solvent.

Introduction to NMR Spectroscopy and its applications

NMR spectroscopy is based on the measurement of absorption of electromagnetic radio-frequency region of roughly 4 to 900 MHz. In contrast to ultraviolet visible (UV-visible) and Fourier transform infrared (FT-IR) absorption, nuclei of atoms rather than outer electrons are involved in the absorption process. Furthermore, to cause nuclei to develop the energy states required for absorption to occur, it is necessary to place the analyte in an intense magnetic field.

A simple NMR experiment produces information in the form of a spectrum, which is able to provide details about the types of atoms, the relative amounts of atoms, the purity and composition of a sample and the structural information about constitutional and conformational isomerisation.

This analytical tool is one of the most powerful tools available to chemists, food chemists, and biochemists for elucidating the structure of chemical species. The technique is also useful for the quantitative determination of absorbing species.

NMR spectroscopy has applications in a wide range of disciplines and area of research such as:

  • Organic, inorganic and physical chemistry
  • Bioengineering and biochemical research
  • Food chemistry
  • Polymer industry
  • Pharmaceutical development and production

Furthermore, commons applications of NMR spectroscopy are structure elucidation, chemical composition determination, raw materials fingerprinting, sample purity determination, compound identification and confirmation, analysis of inter-intramolecular structures, molecular characterization and reaction kinetics.
