Versarien PLC has been re-certified under the US-based Graphene Council's 'Verified Graphene Producer' programme, making it the first producer to achieve that landmark.
The programme is an independent, third-party verification system that involves a physical inspection of the production facilities, a review of the entire production process, a random sampling of product material and rigorous characterisation and testing by a leading, international materials laboratory.
Neill Ricketts, Versarien’s chief executive, said: "We are delighted that Versarien is the first graphene producer to successfully gain re-certification under the Graphene Council's Verified Graphene Producer programme following the scale-up of our graphene production facilities.
"This validation of our technology will enable our partners and potential customers to have confidence that the graphene we produce meets globally accepted standards."
