As the worldwide leader in core holders for NMR and X-ray applications, we are pleased
to announce a new series of composite core holders for use with the low field NMR
instruments. These core holders offer a new composite body of Fiberglass and PEEK.
This new design offers significant advantages as listed below.
We have been providing composite core holders for use with NMR and X-ray instruments
since the mid 1980’s. These composite materials are required, in place of metal
materials, because of their non-magnetic properties. Not any composite fiber can
be used for the NMR application. We use the proprietary Fiberglass material
for these non-magnetic applications. These core holders have developed over time
to include core sleeve material of Aflas for low temperature applications and Heat
Shrink Teflon for high temperature applications. The end pieces of the core holder
are manufactured from non-magnetic metal and the distribution plugs are designed
from PEEK material.
The sample size that is available for testing includes 1", 30 mm, 1- ½", 2" and
certain larger diameters. The measurement sample size is determined by the inner
diameter of the RF coil or bore through the NMR instrument. Based upon these dimensions,
the maximum outer diameter of the core holder is determined. Using the maximum diameter
of the core holder, then the internal parts are designed and the maximum core sample
measurement diameter is determined. We have standard core holders available for
most NMR instruments. When requesting a core holder, please advise the model number
of the NMR instrument that is in use, the RF coil or bore diameter, and the location
of the measurement position within the NMR cabinet. With this information, we
will be able to provide a core holder that will meet the specific application.
