FGMAS probe
NM080006E
Realization of high resolution measurement of semi-solid sample by high speed MAS.
Easy inverse measurement by magnetic field gradient function further.
Feature
"FG(Field Gradient)MAS(Magic Angle Spinning) Probe" is a probe with magnetic field gradient which enables high speed MAS. The target samples are so-called semi-solid sample such as cream, gel, paste samples, or very viscous sample such as ionic liquid, as well as tissue from a living body and sample combined with resin for solid-phase synthesis. Further, high resolution measurement of rubber samples which used to be analyzed by liquid (latex state) NMR or solid NMR, is possible with high speed MAS by using this method.

In most cases of rubber sample, the structure of main chain is already known, and the analysis of side chain is the main.
However, signal coming from side chain is very small, so stable measurement becomes important.
In addition, inverse two-dimensional measurement of 1H observation, the cross peak coming from the side chain is buried in the cross peak coming from the main chain, so, some kind of works to select out or to delete signal coming from the main chain, are necessary.
Measurement Time：
About 35h 45min.
