Nuclear magnetic resonance (NMR) spectroscopy is a well-established analytical technique used to study chemicals and their transformations. However, high-field NMR necessitates advanced infrastructure, even cryogen-free benchtop spectrometers cannot be readily assembled from commercially available components. We demonstrate construction of portable zero-field spectrometer employing magnetometer...

High resolution MRI of live Drosophila was performed at 18.8 Tesla, with a field of view less than 5 mm, and administration of manganese or gadolinium-based contrast agents. This study demonstrates the feasibility of MR methods for imaging the fruit fly Drosophila with an NMR spectrometer, at a resolution relevant for undertaking future studies of the Drosophila brain and other organs. The frui...

more extensive references. These points do not detract from the utility and comprehensibility of this chapter. The novelty of utilizing NMR in biologic systems precludes its presentation in an applied manner. The author of this section appropriately provides a rigorous, though understandable, account of the theory and physics behind this technique. In a logical sequence the reader is introduced...

This article describes a method for improving 1H NMR spectra of aqueous samples containing paramagnetic metals by precipitation metal cations with variety counteranions. The addition hydroxide, phosphate, carbonate, and arsenate to solutions transition such as Fe2+ Mn2+ can reduce line broadening improve the ability spectrometer lock on signal deuterium. is most effective under strongly alkalin...

Macaranga triloba belongs to the family of Euphorbiaceae. Investigation on the dichloromethane extract of flower of Macaranga triloba collected at Hulu Terengganu, Malaysia has yielded four flavanone compounds known as 6-prenyl-3’-methoxy-eriodictyol (1), nymphaeol-B (2), nymphaeol-C (3) and 6-farnesyl3’,4’,5,7-tetrahydroxyflavanone (4). The structures of these compounds were elucidated based o...

Introduction The aim of this study was to compare the accuracy of parameters derived from q-space measurements between a 3.0 T clinical MRI scanner and a 4.7 T NMR spectrometer. In order to do this, measurements were performed on n-decane, at the two systems using similar pulse sequence parameters. Materials and Methods The n-decane is a linear hydrocarbon (C10H22) that gives a diffusion coeffi...
