News of Version 04/01/2012

Free access to the publication “Determination of Reference Values for NIST SRM 610–617 Glasses Following ISO Guidelines”, Jochum et al. 2011.
Fast data input:

If you want to make sure that your results will be included in the next application version of the GeoReM database send your published data directly to the GeoReM team. Please provide your results as an Excel-file in the following form to georem.database@mpic.de In addition we need the corresponding paper as an pdf-file. The data have to contain the analytical method, unit (only µg/g or µg/l for trace elements; %m/m for oxides) and the type of the uncertainty (for example standard deviation, relative standard deviation or 95% confidence level) Different tables are necessary for different analytical methods and various institutions.

New query: chemical criteria based on bibliography, eg lists of all elements published in 2004 and/or published by special authors and/or in selected journals.
Direct access to reference materials by entering a part of the sample name.
For our Chinese colleagues a GeoReM-paper published in Chinese:

Geochemical and Environmental Reference Materials and the GeoRem Database"
Rock and Mineral Analysis 28, 311 - 315 (Chinese Paper)
Flyer

Bibliographic lists now contain item surveys, which give an overview about the analyzed reference materials and the determined items (for papers published since 2006).

Samples can now be selected using 4 new categories (geological, biological, environmental, microanalytical). For each category you can also select a provider (e.g. biological NIST, microanalytical USGS reference materials).

New GeoReM preferred values for OU-6 and BRP-1.

GeoReM now contains a discussion page. Users can ask questions, write answers, give comments etc. Please log in for registration.
GeoReM preferred values of the new USGS GS samples and 91500 zircon.
Considerable increase of number of papers.

current and former versions can be selected. The current version has much larger datasets than the old versions
GeoReM preferred values of further reference materials.
Team: People involved in the development of GeoReM.

This version of the software contains "GeoReM preferred values" (GPV) for some of the TOP 50 samples, as evaluated by us. Values for other samples will follow soon. Our criteria for the GPV are primarily certified data, as well as data from high precision and definitive methods, such as ID-TIMS. The GPV can be obtained by the query "Samples (GeoReM preferred Values)" for samples, where preferred values are now available, or "Samples and Materials (published Values)" with possible links to "GeoReM preferred Values".
Top 50 most frequently requested reference materials can be listed.
Top 10 most clicked reference publications can be listed.
"Query by Chemistry": isotopes and isotope ratios are in one common list ordered by mass number.

Query by methods and Institutions is possible.
Enhanced uncertainty information.
Addresses of institutions.
