An NMR tube is a thin glass walled tube used to contain samples in nuclear magnetic resonance spectroscopy. Typically NMR tubes come in 5 mm diameters but can also range from 10 mm to 3 mm samples. It ...

To clean NMR tubes after the NMR experiments are over ... For samples that are not dissolved by acid (e.g., some polymers), a solvent that swells the sample may be used and a pipe cleaner might to ...

Larger tubes are preferable for samples with limited solubility ... essential for product development and quality assurance. In polymer science, NMR is used to determine molecular weights, chain ...

Add 700 ul of the filtered solution to a clean 5 mm NMR tube, and cap and label the tube. For the liquid samples, use about 700 ul spiked with 1-2 % TMS. As a general guide, a sample concentration of ...

One of the reasons for its widespread popularity is because NMR is able to provide valuable information on the molecular characteristics of polymers under user-friendly conditions, with a wide range ...

has recently attracted attention as a highly sensitive NMR measurement method for analyzing polymers. We recently investigated DNP-NMR for insoluble polymers, particularly cross-linked polymers ...

For example, if you want to run the LCMS you must provide columns, sample vials, and mobile phase or if you want to run the NMR you must provide the NMR tubes and deuterated ... where DSC is used is ...

In a recent study, researchers explored the use of solid-state DNP-NMR to analyze insoluble polymers like cross-linked polystyrene and polyphenylene sulfide. The findings offer new insights into ...

A recent review article in Polymer Journal discussed using dynamic nuclear polarization (DNP) with solid-state nuclear ...

In addition, this user-friendly instrument makes it possible to highlight key concepts and introduce novel experimental methods, such as NMR tube reactions. The Nanalysis 60e benchtop NMR eliminates ...

Polymer Chemistry Communications contain novel scientific work of such importance that rapid publication is desirable. Authors should briefly indicate in a covering letter the reasons why they feel ...
