NMR Analyzer, model PQ001 for Spin Finish

The NMR Analyzer, model PQ001, for Spin Finish

The model PQ001-Spin Finish produced by Niumag is, up to now, the only FT-NMR instrument to analyse opu in fibres. It needs 5 to 6 hours to get a result using the traditional extraction method. But the industrial production of fibres is high speed and continuous. In order to resolve possible production problems it is necessary to use other techniques, that are much quicker and less costly and that do not use chemical products. The NMR method is very quick, not destructive and does not need chemical solvents. It only needs a few seconds after the introduction of the sample fibres to obtain the resultado. The advantages of the NMR method are the following:

• Much better monitoring of the quality during the production process.
• The results are quickly obtained allowing the correction of problems in time during the production process.
• Much less expensive.
• It does not need chemical products reducing the need for special insurance.
• It should lead to a reduction in the number of employees.
• Direct economical benefits.
• Precise measurements are necessary to control the oil used.
• The method is completely green without any damage to either the sample or the environment.
• Quick measurements needing only 3 minutes to get the result of a single sample.
• Wide opu range. It is possible to obtain the precise opu content in the range from 0,1% - 100%.

• Very respectful with the environment (no chemical solvents nor dangerous products).
• Uses an industrial bench top computer.
• The instrument is completely designed in modules making for easy maintenance.

Characteristics

• One box design saves a lot of space and offers a more convenient operation.
• The spectrometer NMdigi made specially by Niumag guarantees an excellent stability and offers powerful instrument functions.
• Based on an industrial computer and professional (ICC), the data processing is very quick and with its anti-blocking function offers a better stability.
• The analysis is not destructive and allows for the total recovery of the sample.
• A large permanent magnet that offers stability and reliability of the results.
• The probe diameter is 15 mm. and can be increased to 25 mm, which gives a better signal sensitivity and reduces possible errors.
• Correction of the central frequency is automatically applied as are the settings of the pulse widths for the 90° and 180° pulses (at the same time using the manual function).
• Uses Windows as the operating system which offers convenience and huge capacity database utilities including the classification, comparison, calculations and other functions.
• Excelent repeatability. By using the Niumag software the resulting error of the same sample in the same conditions on different occasions (such as two weeks separation) should be less than 0,5%
• The Calibration is easy and stable.
