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 Triple Resonance Broad Band Probe (TBI)

The Bruker 500 MHz NMR with the TBI probe can be used for a wide range of experiments to meet research needs.  Some of the characteristics include: Nuclei: optimized for ¹H, indirect ¹³C and ¹⁵N. This system is well suited for¹H, and a plethora of 2D experiments, such as COSY, NOESY, TOCSY, ROESY, HMQC, HSQC, and HMBC. Samples best suited to analysis on the Bruker Avance III HD are very low concentration¹H, samples for which ¹H is a priority.
