Polyurethanes

Polyurethanes are important materials in many aspects of our day-to-day lives – from the automotive industry to coatings, construction, packaging, textiles, footwear – the range is truly impressive.  With the industry continuing to exhibit significant growth, there is a concomitant need for improved productivity and more rigorously defined quality control (QC) methods that can help improve batch productivity and save producers time and money.  If you want to learn how benchtop NMR can help you determine the purity of all key raw materials used in polyurethane production, such as catalysts, diisocyanates, extenders, crosslinkers, UV stabilizers, antioxidants, or flame retardants, as well as confirm the number of repeating units, mixture compositions, number-average molecular weights, and even hydroxyl values for polyols, please contact us.

Which benchtop NMR model works for me?

60 MHz: The perfect instrument to analyze your raw materials to confirm their structures, purities, and many other important characteristics within minutes. Additionally, the embedded computer makes this the most compact benchtop NMR instrument on the market, ensuring that this technology can be added to your laboratory without impacting your current workflows or requiring a large space.

100 MHz: The most powerful benchtop NMR instrument available provides you with all the advantages of the 60 MHz, in addition to increased sensitivity and peak dispersion, making it especially useful for the analysis of more complex raw materials, mixtures, blends, and finished polyurethane products, which might benefit from the additional information that can be obtained from a stronger magnetic field.

NMR Software packages

Installation Qualification/ Operational Qualification (IQ/OQ)

Allows for the qualification of Nanalysis benchtop NMR instruments at the customer's site at desired intervals, including immediately after installation, after moving the instrument, or over time to ensure that the instrument is performing to specification and to help with regulatory and GxP compliance.

qNMR Software Module

A new, automated, easy-to-use software module allowing you to create and edit method to automate routine qNMR assays and allowing technicians to collect data effortlessly.

  • The qNMR module has its own dedicated tab to create, edit and/or manage qNMR methods.  The administrator can set up acquisition parameters, integral ranges, etc. and name the method something that is easily identified, to allow any user to recall the method and run it as specified.  To personalize the method to the analysis, the analyst can include their name, the calibrant weight and purity, and the sample name and/or batch identifier so that they can be easily reviewed and identified when the results are audited.

    Once a qNMR method is developed and saved it can be used in routine qNMR evaluation.

    *Compatible with the Nanalysis-100 and Nanalysis-60 only.

    A typical qNMR module workflow includes the following steps:

    1. Develop and save the qNMR method

    2. Load the desired qNMR method

    3. Set sample and analyst details

    4. Acquire the data

    5. Get the purity results
