For example, proton, fluorine, phosphorus NMR can be used to characterize polymeric products including:

• Observe reaction completeness and uniformity

• Qualify the relative composition of the structural components

• Quantify the relative percentages of structural isomers

• Observe the presence of stereoisomers and determine polymeric tacticity

Even though polymer NMR has been done on high-field instruments for years, it can be expensive and, depending on the accessibility and availability of the NMR spectrometer, time consuming.

If you’re interested in software packages that ease incorporation of your benchtop NMR, please inquire about:

• Installation Qualification/Operational Qualification (IQ/OQ) software modules

• Advanced User interface for optional application programmatic interface to write own pulse programs or control instrument remotely-

• Developments of CFR 21 Part 11 Compliance.

“Now we run all our products in our own R&D lab – not only saving us time and money, but also giving us flexibility to acquire conformational NMR data on samples that we wouldn’t have deemed necessary to outsource.”
