JEOL 400 MHz NMR
The JEOL 400 MHz NMR (Nuclear Magnetic Resonance) is an excellent tool for teaching and research. Some of the characteristics include: Nuclei: 1H, 13C, 19F, 15N, 31P, Auto-tune unit on probe, and Basic 1-D plus DEPT, ROSEY, NOESY, TOCSY, COSY, HMQC, HMBC, and HSQC. It also has an ECS-400 console, “pulsed field gradient amplifier, selective 2H and 1H gradient shimming, fast settling temperature controller, 400MHz magnet, autotune-ready, broadband, gradient, high sensitivity probe, [and] delta software featuring Cyber-Enabled NMR acquisition” (jeolusa.com). Samples best suited to analysis on the JEOL Eclipse ECX-400 are samples for which analysis of 15N, 31P, and 19F are priority.
Bruker 500 MHz Avance III HD with Cryoplatform NMR
The Bruker 500 MHz with Cryoplatform NMR is “the ultimate NMR platform for life-sciences and materials research. Robust, automated and easy-to-use, it is the ideal NMR analysis system for the pharmaceutical, biotech, and chemical industries” (bruker.com). Some of the characteristics include: Nuclei: Cryoplatform optimized for 1H, indirect 13C and 15N, Cryoplatform increases sensitivity toward 1H, and COSY, NOESY, TOCSY, ROESY, HMQC, HSQC, and HMBC. Samples best suited to analysis on the Bruker Avance III HD are very low concentration 1H, samples for which 1H is a priority, or bio-molecules (e.g. proteins, carbohydrates).
