NMR Analyzer modelo PQ001

The NMR Analyzer, model PQ001

Descripción

The NMR Analysis System, model PQ001, has been specially designed to offer a superior analysis and save costs. Thanks to its reliability and precision the PQ001 has been approved by experts in this field. As a special high performance analyzer with a very competitive price the instrument is ideal for the analysis in the petro-chemical, food, energy, biological, agricultural, botanical fields and more...

With the minimum of components the PQ001 is easy to set up and maintain. In the electronic unit the modules are organised in groups that are accessible via the back panel. The advanced elctronics allow the update of the instrument using a DVD and a log in its own web page which is accessible using Internet.

Characteristics

• One box design saves space and offers a more convenient mode of operation.
• The NMdigi spectrometer, developed specially by Niumag, guarantees an excellent stability and powerful instrument functions.
• Based on an professional industrial computer (ICC), the data processing is very quick and with its anti-blocking function it offers high stability.
• The analysis is non destructive which allows the total recovery of the sample.
• It uses a large permanent magnet that offers stability and reliability of the results.
• The diameter of the probe is 15 mm. and can be changed for one of up to 25 mm. which increases the sensitivity of the signal reducing the possibility of errors.
• It applies automatically the correction of the central frequency and searches for and applies the width of the 90º and 180º pulses.
• It uses Windows as its operating system which offers convenience in its operation especially for its capacity to manage huge databases that can realise the classification, comparison, calculations and other functions.
• Excellent repeatibility. Usng the software supplied by Niumag, the resulting error for the measurement of the same sample in the same conditions but at different times (a couple of weeks) will be less than 0,5%
• The Calibration is easy and stable needing only 3 to 6 samples to achieve an excellent correlation.
• Rapid analysis needing only seconds to analyse fat and moisture in a sample.
• Automatic search and adjust of the resonance frequency and the 90º and 180º pulse widths.
• Good reliability assuring that the standard deviation does not excede 0,5%
• The operation of the PQ001 is easy and confortable and the samples need none or little preparation.
• Accessories include variable temperature and variable pressure.
