Nuclear Magnetic Resonance (NMR 400 MHz)

Make & Model – JEOL & JNMECS400

ECS Narrow Bore Spectrometer (400) FT NMR System is a versatile high-performance system that utilizes the latest digital and high-frequency technologies. The JNM ECS400 series FT NMR System features improved operability and small installation space, both of which are required for routine NMR systems. It’s a two-channel spectrometer., Room-temperature shim: Digital matrix shim, 21 items controlled.
- Variable temperature range: -140 to +180-degree C.
- High Band (1H /19F) amplifier (HF): 50 W,
- Low band (or Broad) band amplifier (LF): 150W
- Gradient Strength: 30G/Cm @ 10A (Standard)
Working Principle:

The principle behind NMR is that many nuclei have spin and all nuclei are electrically charged. If an external magnetic field is applied, an energy transfer is possible between the base energy to a higher energy level (generally a single energy gap). The energy transfer takes place at a wavelength that corresponds to radio frequencies and when the spin returns to its base level, energy is emitted at the same frequency. The signal that matches this transfer is measured in many ways and processed in order to yield an NMR spectrum for the nucleus concerned.

Fig., relates to spin- ½ nuclei that include the most commonly used NMR nucleus, proton (1H or hydrogen-1) as well as many other nuclei such as 13C, 15N and 31P. Many nuclei such as deuterium (2H or hydrogen-2) have a higher spin and are therefore quadrupolar and although they yield NMR spectra their energy diagram and some their properties are different.

ECS Standard Software
- The client system of the ECS, Delta, provides versatile data processing and easy to-use interfacing with the NMR spectrometer. The Delta software application, constructed on a highly virtual architecture, is easily transported to various operating systems, ensuring that the operating environment lasts despite rapid changes in computer technology. Supporting the standard graphics environment, OpenGL, the Delta software can efficiently perform routine data processing. The JNM-ECS FT NMR System is operated under both the high-grade, stable hardware and the easy-to-use superior software, in spite of being a small, low-cost system. Thus, the JNM-ECS provides the highest-level NMR research data while greatly reducing the analysis time required for routine NMR measurement
Vibration Proof Table
- This is an air-damper-type vibration proof table used with a 400 MHz superconducting magnet (SCM) for an NMR system
400MHZ TH5Probe
- This probe is used for ¹H and multinuclear NMR observation while irradiating ¹H and applying a pulsed magnetic field gradient to a sample using a 5 mm sample tube in the FT NMR system. By using the optional Auto Tuning Unit, you can automatically tune the probe for the multiple nuclei.
400MHz H5X Probe
- This 5mm probe is optimized for ¹H observation. This probe is therefore recommended for ¹H measurements including inverse experiments (¹H observed 2D experiments). This probe is compatible with the Auto tune controller thus consecutive measurements can include change of nucleus as well as different experiments.
STACMAN ASC64
The “Auto Sample Changer 64” can be installed in an FT NMR system, which is configured with one of the superconducting magnets (SCM).
- This sample changer can be used to automatically change the sample tube containing the sample for measurement by commands from the host computer
Variable Temperature Accessory: Liquid Nitrogen based
- VT control range: -100 ^oC to + 150 ^oC., Temperature setting steps 0.1 Deg C. Low temperature unit include suitable liquid nitrogen Dewar. Low temperature limit: - 100 Deg C. The low temperature unit is complete in all respects. This all function controlled under host computer.
Auto Tuning Unit
- Auto tuning unit comes as a standard, which will be helpful in doing Automatic Tuning and Matching for the nuclei under study for liquid samples.
