The new JNM-ECZS NMR spectrometer from JEOL has functionality and performance normally only found on high end instruments, yet in a compact, space saving design.
Through the combination of advanced software with highly reliable hardware, all routine daily measurements can be automated.
Using ultra high sensitivity Autotuneprobes, including the optional SuperCOOLprobe which features cryogenically cooled technologies, JNM-ECZS affords the world`s highest sensitivity in its class.
The high performance can be demonstrated in many application fields.
The JNM-ECZS spectrometer incorporates the instrumental performance normally only found in high end research models. However, the main spectrometer chassis has a footprint of only 57% of comparable instruments, thus making it the smallest NMR spectrometer operating at 400MHz in the world. In combination with super conducting magnets (SCM) which feature ultra-small stray magnetic fields, a more flexible installation layout is possible.
*Compared to 400 MHz NMR spectrometers as of October 2016.
The JNM-ECZS spectrometer is equipped with JEOL’s newly-developed Smart Transceiver System (STS), which uses a fusion of the latest integrated digital circuit and high frequency technologies. By implementing the STS technology and the multi-sequencer which has been cultivated from earlier models, the standard 8 frequency sources are freely controllable regardless of whether they are synchronized or not. It can not only execute all pulse programs used in daily routine analysis work in a stress-free manner, but also execute very complex pulse programs with ease. Sequence editing is also possible.
The JNM-ECZS spectrometer provides fully digital control of r.f. generation and NMR lock and shim units, in order to maintain the high stability essential for high quality spectra. The excellent stability of JNM-ECZS can be demonstrated in its power of solvent signal elimination and difference spectra measurement, enabling the acquisition of many types of NMR spectra beautifully and easily.
The ROYALprobe has been designed based on the essence of JEOL’s probe technologies and is the standard probe supplied with JNM-ECZS. It achieves a 1H sensitivity approximately double that of existing auto tune direct detection probes. Users will benefit from both the ease of use and a much reduced measurement time particularly in a modern NMR measurement facility which requires speed and performance. In addition, alternative probes such as cryogenic probes and triple resonance probes are available as options. Please talk to your local JEOL specialist for your application.
The JNM-ECZS spectrometer uses the latest version of “Delta” NMR software for both spectrometer control and for data processing. The excellent automation interface of Delta, together with gradient shimming applied as standard for each sample, ensures automatic measurements yield optimized resolution in a simple operation. When combined with an auto sample changer and auto tuning, all daily and routine measurements can be automated.
The JNM-ECZS spectrometer is truly a networked device. The spectrometer can be operated separately from the operation terminal and can be controlled from any computer on the network
The head amplifier chassis has various functions related to probe and the super conducting magnet. A touch-panel display is located on top of the head amplifier chassis, offering an intuitive user interface. During probe tuning, reflection dip and reflection value are indicated, whilst during cryogen refilling, the actual level of cryogen in the magnet is indicated in real time. It makes the routine maintenance related to probes and super conducting magnet convenient and efficient.

The spectrometer features enhanced functionality, ease of operation,and an attractive design.
The anti-vibration mechanism and base plate that JEOL uses for SCMs, are designed to reduce minor vibrations coming from the floor that adversely affect NMR spectra. However, this highly reliable anti-vibration mechanism is the only one used by NMR manufacturers to withstand the great earthquake of 2011 and prevented damage to JEOL SCMs. JEOL’s anti-vibration mechanism has also prevented damage to SCMs in previous earthquakes.
By combining a low point of gravity from the base plate held by anchor bolts, when disaster strikes, the risk of damage can be reduced to the minimum.
