We've also used the Mnova software which has global spectrum deconvolution. It will depend on the actual sample, but reference deconvolution worked well for us. ML: We have done a lot of peak deconvolution and yes, it does help you in analyzing the data for certain samples. Q: Will peak deconvolution help in peak resolution for this benchtop NMR? You don't have to look at the whole spectrum, what you do need to look at is the part of the spectrum that's easy to get at, and that gives you the answer you need. ML: That's an excellent example of the way benchtop NMR can be slightly different from the way that a lot of people think of NMR - that you're concentrating on what you can use to get the information most easily. The sensitivity for those systems is in the aliphatic region which is messier for polymers in general. Propylene is hard to do with NMR because of solubility issues so you run into the same problems that you run into at high field. We've done some work with an industrial partner looking at some polypropylene in the low field instrument. I'm assuming that we're talking about polypropylene. This is something that we would love to discuss with people.Д«B: I will add more to the vinyl co-polymer systems. For example, although this isnвЂ™t a vinyl copolymer, you can do poly(styrene-co-butadiene) polymers and polymer composition, but it will depend on the type of levels that you're looking at and the type of sample that you're using.

Is the sensitivity good enough? That is an excellent question and it really does depend on the sample and the application. We're interested in learning more about the kinds of applications in the polymer industry that people are interested in. ML: There are certainly applications for vinyl co-polymers, and I'd like to talk to you about the blends and alloys. Q: Are you aware of low-field NMR applications for vinyl copolymers, blends, and alloys, and is the sensitivity good enough? IвЂ™m not sure that there's a good practical limit other than what you can get in an NMR tube. We have run cross-linking network polymerizations inside NMR tubes in the Pulsar where we aren't tracking the polymer necessarily, but we're tracking the monomers, and those work all the way up until it's past its gel point. For the low field, we haven't tested beyond that. Q: What are the typical average molecular weights of the polymers you analyze and what is the highest molecular weight polymer that you think would be possible to analyze?Д«B: Most of the materials that we make can be from 5,000 grams per mole at the low-end to 150,000 grams per mole at the high-end.
