Nuclear Magnetic Resonance (NMR) is a ubiquitous spectroscopy method used by analytical chemists to obtain both qualitative and quantitative information about functional groups, molecular backbone and the chemical environment of nuclei in a molecule.
Teaching of basic NMR theory is part of the Chemistry Undergraduate curriculum throughout the world and analysis of NMR data is a fundamental part of most undergraduate chemistry teaching labs. Despite this and in contrast to many other spectroscopic methods, undergraduate students are rarely given the opportunity to operate a spectrometer due to the complexity and cost of the instrumentation. With the advent of the benchtop NMR spectrometer, Pulsar, this will change … Pulsar is an affordable, benchtop, cryogen-free NMR spectrometer that offers performance without expensive liquid helium making it suitable for virtually any chemistry laboratory and ideal for teaching NMR to undergraduates.
Professor David Haddleton in the Department of Chemistry, University of Warwick, UK has trialled Pulsar in his undergraduate laboratory ...
“Pulsar was introduced into a year three synthetic chemistry undergraduate laboratory at Warwick and used to follow real time organic, inorganic and polymer reactions taken direct from the reaction medium. Installation was simply plugging in the 13A plug and leaving to warm up overnight. The absence of the requirement for deuterated solvents and the ability to collect excellent quality FT NMR in a single pulse in less than 2 minutes with instant exportation into all NMR software was incredibly valuable for our students. The experiment was easier and quicker than a TLC (Thin Layer Chromatography) with massively more information. The instant availability of the data proved invaluable for the selection of experiments required on the standard high field NMR spectrometer, thus freeing up instrument time and greatly reducing the need for time on more expensive instrumentation. This is a must for undergraduate laboratories and research laboratories without access to high field instrumentation.”
