Replacement magnet for INOVA 300 NMR spectrometer

点击翻译按钮获取中文摘要

The original magnet belonging to the INOVA 300 NMR spectrometer in the Department of Chemistry at UNB is beyond repair. We have considered three replacement options for this magnet; viz. a new Varian/Magnex magnet; a refurbished Oxford Instruments long-hold magnet; and a refurbished Varian/Oxford ALOX magnet. The latter option represents the most cost-effective solution, and will permit us to bring the 300 MHz instrument back into much-needed use. Prior to the demise of its magnet, the 300 MHz spectrometer was the primary walk-up instrument used by all graduate students, post-doctoral fellows and many undergraduates (approximately 50 researchers). This instrument was used around the clock prior to the failure of the magnet; we are currently relying on an ageing 1992 vintage 400 MHz UNITY instrument for all NMR spectroscopy carried out in the Department.
