Hi Dovile Karloniene

just check the databases like https://rrr.bam.de/RRR/Navigation/EN/Reference-Materials/COMAR/comar.html

http://georem.mpch-mainz.gwdg.de/

or others...

depends on what elements you need to calibrate!

Bruce Neagle

Because I live in North America I would use a USNIST (National Institute of Science and Technology) or USEPA (Environmental Protection Agency) CRM's. But it depends on your analyte (Hg perhaps?).

Dovile Karloniene

Thank you for information, will check these databases! Well, at this stage, the main focus is on Zn, Cu, Pb, Cd, Cr, Mn and macro-elements.
