CryoProbe Applications

Polymers

The Polymer CryoProbe is specifically designed to revolutionize polymer NMR analysis. By offering up to a 4 fold increase in sensitivity and a z-gradient this probe promises to reveal information on polymer structure that elutes the technology currently employed in most laboratories. Sized to accept 10mm samples and with an extended temperature range this probe incorporates specific features of importance to polymer researchers. With a temperature range of 0° to 135°C the use of high temperature NMR to increase molecular motion and provide narrow linewidths is achievable. Although configured optimally for ¹³C observation the dual configuration allows for excellent ¹H observation as well. Being equipped with a z-gradient this probe is prepared to use pulse field gradient experiments to provide detection of 2D and 3D NMR cross peaks from minor structural components in organic polymers all with remarkable sensitivity or speed.

Uses of this probe include:

Polymer chain structure analysis
Competitive polymer product analysis
Additive identification and quantification
Compositional analysis of polymer formulations
Branching and unsaturation content analysis
Sequence distribution and tacticity analysis
Kinetics and thermal dynamics analysis
