Lab-Tools also develop, operate and sell NMR Cryoporometry
apparatus that is optimised to measure pore sizes,
pore size distributions and pore volumes and to study
materials that are structured on a sub-1nm to over 1μm length
scale. Most finely porous
materials are suitable for such studies, provided that a
liquid can be added or
is already present.

This apparatus is based on wide-temperature range
NMR relaxation spectrometers with ultra-precise
temperature control. A new generation of NMR instrumentation VT
is now ready for release. Peltier or gas cooled
probes are available from Lab-Tools for use with the Lab-Tools NMR spectrometer, or to retro-fit
industry standard NMR spectrometers, for your own NMR
Background information on the Cryoporometric technique is

Lab-Tools performs Contract Measurements on Porous
both academia and industry.
Lab-Tools performs research to study the properties
liquids and their ices / gas hydrates in structured
materials and at interfaces.
The studies we perform are relevant to :
Understanding the properties of water/ice at
hydrophilic/hydrophobic and biological interfaces.
Understanding how to increase recovery from oil and gas
Determining the properties of methane hydrate in model
and real marine porous systems,
Informing research on porous catalyst support systems,
Studying properties that affect the frost resistance of
cement and fired clay,
Informing high performance nano-structured battery
Helping predict the longevity of biochar for carbon
Lab-Tools performs industrial contract analyses and also
joins with other bodies such as universities to perform
Lab-Tools has close ties with academics at a number of
Lab-Tools performs NMR contract
analyses, including both measurements of dynamics/mobility/rigidity using NMR relaxation, and of Pore Size Distributions using NMR
Lab-Tools has successfully measured pore sizes
in a wide range of porous materials, including
oil and/or water wet materials. NMR
Cryoporometry is one of the few techniques that
can be applied to materials that can not be
dried out without losing their structure. The
technique is non-destructive, and can be used to
follow evolution of pore structure for evolving
The Lab-Tools pore-size distribution measurement
range extends from sub 1nm to over 1µm. NMR
Cryoporometry measures both the total pore
volume and the pore volume distribution as a
function of pore diameter.
We frequently find that NMR Cryoporometry (NMRC)
may be preferable to more established methods
such as BET gas adsorption or DSC thermal
porisimetry, and can now also provide
information on both pore diameter and pore
throat size, unlike Hg Intrusion, which just
measures the pore throat.
NMR Cryoporometry measurement costs are very
Cost per sample depends on the pore-size range to be covered, and
precision needed, but goes down markedly for
