The PMX60SI is a 60 MHz proton measurement high-sensitivity high-resolution NMR developed in response to a market need for simplified NMRs . It is designed with easy operation, minimum maintenance and low running cost as the basic consideration. Employing a compact permanent magnet, the PMX60SI is easy to install and conveniently usable as a routine work NMR.

Thanks to its many built-in features, the PMX60SI can be operated easily by anybody, allowing even an NMR novice to obtain quality spectra. This instrument, based on the circuitry of the PMX60 with proven reliability, employs IDCs and transistors subjected to strict quality control. What is more, as its permanent magnet is strictly temperature controlled and magnetically shielded, the instrument can be installed in an environment not better equipped than an ordinary laboratory.

The PMX60SI can thus fully meet a wide variety of purposes such as routine measurement, training, quality control of industrial products, and use as your second or third NMR or as a support instrument for FT NMR.

A wide variety of functions provided as standard

Higher sensitivity assured by the newly developed “Super Insert” probe

The adoption of this JEOL-developed detection coil has improved the sensitivity about 30%.

Permanent magnet with high resolution and stability

Despite its compact size and light weight, the PMX60SI magnet provides excellent field uniformity, allowing a resolution as high as 0.4 Hz to be obtained with ease. Furthermore, since the permanent magnet is strictly temperature controlled and magnetically shielded, it can stably maintain high resolution over a long period of time.

Automatic TMS controller built-in

When samples are changed, it is conventionally necessary to adjust the TMS peak position to the zero point prior to spectrum recording. The Automatic TMS controller permits the TMS peak to be automatically recorded at the zero point even under different magnetic susceptibilities and solvent effects … with the touch of a single key.

Measurement at a single touch of feather-touch keys

The PMX60SI employs color-coded feather-touch keys, allowing even an NMR novice to make error-free measurement. The white keys are used for standard settings. Each of these feather-touch keys employ a digital IC circuit and an LED for better reliability and operational ease.

Samples

a)       1% Ethylbenzene

b)       Transcroton aldehyde

c)       20% Acetoaldehyde

d)       90% Ethylbenzene

e)       Mixture sample [CHCI ₃ , CH ₂ CI ₂ , O(CH ₂ · CH ₂ ) ₂ O, CH ₃ CCI ₃ , (CH ₃ ) ₂ CO, C ₆ H ₁₂ , Si(CH ₃ ) ₄ ]

Easy sample tube setting utilizing air cushion

The PMX60SI employs a mechanism utilizing compressed air for simple and safe setting of sample.

No specific installation environment required

Consisting of a compact spectrometer console and a strictly temperature controlled and field shielded permanent magnet, the PMX60SI can be installed in an ordinary laboratory. The power consumption is as small as 150 W, making the instrument an energy-saving one.

Maintenance-free construction

The burden for maintenance has been greatly alleviated by the use of a large number of strictly quality-controlled highly reliable ICs, keyboard switches with less mechanical components, and logic electronic circuits.
