Procurement of suitable Suppliers that can provide access to a small-scale flow reactor instrument or test rig to perform characterisation experiments on solid materials. The test requirement is to perform absorption breakthrough analysis to verify the effectiveness of getter materials at removal of contaminants from a flowing noble gas stream. The contaminants involved are hydrogen, carbon monoxide, carbon dioxide, oxygen & nitrogen. The supplier will be responsible for providing access to or procuring the necessary instrumentation to host these tests and performing a programme of tests for four sample materials with two gas mixtures.
