Literature review of 7200 geoanalytical publications for the year 2020.
628 selected articles with summaries of target analytes, relevant reference materials and producers.
Selected publications include data obtained by new analytical developments and improved analytical protocols for established RMs, and identifies recently developed RMs for specific scientific topics.
Here, we present the Geostandards and Geoanalytical Research Bibliographic Review 2020—an overview of scientific publications in 2020 that contribute important data for geoanalytical reference materials (RMs).

The use of RMs for calibration and quality control purposes of analytical techniques is essential for geoanalytical research and related scientific fields to obtain reliable results. This review encompasses RMs used in traditional geochemistry as well as for palaeoclimate research or environmental and other related applications. The systematic research comprises more than 7200 individual publications from nineteen scientific (i.e., peer-reviewed) journals. Additionally, some specific publications of further journals are included. A total of 630 of these articles present measurement results for RMs, which represent about 9% of all surveyed publications (Table 1; Figure 1). In 2020, publications included data that were obtained by new analytical developments or improved analytical protocols for established RMs. In addition, this year’s survey identified some recently developed RMs for various scientific topics. All data we refer to in this review have been compiled in the GeoReM database that is freely available online (Jochum et al. 2005, http://georem.mpch-mainz.gwdg.de). The recent Application Version 30 of GeoReM (as of January 2021), which includes more than 3800 RMs of numerous providers worldwide, will be replaced by Application Version 31 (March 2022). Appendix S1 contains the full list of publications surveyed for 2020, which are the topic of this review and also are included in the GeoReM database in alphabetical order. The GeoReM reference citation in Appendix S1 is preceded by a key code: at first, there is serial number followed by the GeoReM-ID, which enables fast and easy queries within the database. An overview of the names and abbreviations of RM providers is given in Appendix S2.
