Bespoke Characterisation
We love a challenge! We are willing to provide an innovative solution to meet your demands. We offer bespoke characterisation facilities that require building dedicated testing systems. These include thermal conductivity and capacity for materials, high-temperature catalyst attrition studies. We have recently completed challenging in-situ X-ray absorption (XAS) studies, over a large temperature range, at the Diamond Light source in Harwell.
Case Studies
Temperature Programmed Oxidation of Cu Catalyst | Case Study
Background Temperature programmed oxidation (TPO) is a versatile materials characterisation tool used in catalysis for the elucidation of surface chemistry in catalytic materials. The underlying principle of the technique is simple, hydrogen or oxygen are passed over...
Pyridine Chemisorption analysis service for characterisation of acid sites
We have recently published a case study on the pyridine chemisorption services we perform which determine the number of the corresponding acid sites in a material.
Characterisation-directed kilo catalyst scale-up
We manufactured 10 kg catalyst using characterisation to validate the scale-up procedure from lab to manufacturing processes.
X-Ray Absorption Spectroscopy (XAS)
We completed in situ synchrotron studies of a customer’s catalyst at the Diamond Light Source Facility.
