To encourage the worldwide use of available Certified Reference Materials (CRMs) for measurements of nutrients in seawater, five new lots of CRMs were produced and distributed globally as an activity of the Scientific Committee on Oceanic Research (SCOR) Working Group #147. The production process was the same as that used for commercially available CRMs, and Atlantic Ocean seawater was also used, considering the potential usefulness of such CRMs to countries bordering the Atlantic Ocean. Between 2016 and 2021, 4186 CRM samples were provided to 48 institutions as part of a promotional campaign for the wider global use of CRM. Herein we discuss the challenges of preparing these CRMs and sustaining their distribution and accessibility.

摘要

To encourage the worldwide use of available Certified Reference Materials (CRMs) for measurements of nutrients in seawater, five new lots of CRMs were produced and distributed globally as an activity of the Scientific Committee on Oceanic Research (SCOR) Working Group #147. The production process was the same as that used for commercially available CRMs, and Atlantic Ocean seawater was also used, considering the potential usefulness of such CRMs to countries bordering the Atlantic Ocean. Between 2016 and 2021, 4186 CRM samples were provided to 48 institutions as part of a promotional campaign for the wider global use of CRM. Herein we discuss the challenges of preparing these CRMs and sustaining their distribution and accessibility.
