A Novel Approach for the Environmental Study of Organisms in their Natural State
28 Mar 2016This application note demonstrates the capabilities of multiphase NMR in providing molecular analyses of complex heterogeneous samples. Typical analytical approaches to environmental research rely on sample processing, such as extractions that provide only a selective window into the true natural state. The integration of concepts from different fields of NMR spectroscopy enables us to produce a novel comprehensive approach that can be used to study and differentiate between the various phases in a heterogeneous sample as well as identify the key structures and their molecular interactions within each phase.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.NMR and EPR SpectroscopyNuclear magnetic resonance (NMR) spectroscopy is used to resolve the local chemical environment of atomic nuclei with spin, revealing information on molecular structure, dynamic processes and chemical reactions of organic molecules, from proteins to synthetics. Electron paramagnetic resonance (EPR) also known as electron spin resonance (ESR) spectroscopy is used to detect and quantify paramagnetic species in a sample, including free radicals as transition metal ions. By immersing the sample in a strong magnetic field, both NMR and EPR spectrometers probe the sample with either radio waves or microwaves respectively. A range of benchtop, solid-state and time domain NMR spectrometers & EPR spectrometers are available, as well as NMR tubes, NMR solvents, software, coils, and magnets.
