VARIAN'S $5,000 NMR SYSTEM: the teaching machine that moonlights as a chemical analyst 1.1. Past experience plus new design technology yields EM-300 system.Thanks to the efforts of Varian Anaspect, a moderate performance, 30 megahertz NMR system in the $5,000 price range is now a reality (Fig. 1, below). Varian Anaspect is a natural extension of the fine work carried on by Varian's Analytical Instrument Division, long recognized as a world leader in the design and manufacture of highly sophisticated research instrumentation. 1.2. Inherent value of such a low cost, moderate performance NMR system. A system such as Varian Anaspect's EM-300 serves two important purposes:
Figure 1. Photograph of Varian Anaspecfs new 30 MHz EM-300, a 55,000 moderate performance NMR system designed for both instruction and routine chemical analysis applications. Shown here with optional recorder.
First, as a viable, simply designed and highly dramatic training tool for instruction in both basic chemistry and experimental method, which performs an analysis in less than five minutes (Fig. 2, above); and... Secondly, as a highly stable, minimum-adjustment tool for routine analysis which frees sophisticated machines for more complex chemical problems.
Figure 2. Spectrum for p-methoxyacetophenone shows performance for a typical compound of Varian Anaspect's low cost 30 MHz NMR system, the EM-300.
Understandably, it is no small task to translate the electronics of systems ranging from $20,000 to $100,000-and-up into a moderate performance, low price version such as the EM-300. It requires not only a complete understanding of the technique, but a keen sensitivity for the needs of student, instructor and chemical analyst who will be the end users. 1.3. Spectra, design information available. Complete information on the new EM-300 NMR system as well as typical spectra are yours for the asking.
