			*December 2023. Finally, following on discussion at both canSAS-VIII in Japan and canSAS-X at Berkeley, a new Q standard for SAXS has been developed at NIST which will be available as an SRM by Joseph Kline. In a next step we are aiming to organize a round robin with this standard in 2024. More details will be on the [[round_robin \| round robin]] page as they become available.
