  • The certification of the contents (mass fractions) of Al, Ca, Cl, Fe, K, Mg, Mn, Na, P and S in freshwater : Low element content CRM 398 - High element content CRM 399

Abstract

This report describes the preparation of two freshwater reference materials (one with a low element content CRM 398, the other with a high element content CRM 399), the homogeneity and stability studies, and the analytical work for the certification of the contents of some elements. It contains all the results and details of methods used to certify the contents (mass fractions) in CRM 398 and CRM 399 of: Al (36.3 and 207 ng/g), Ca (30.0 and 79.2 micro-g/g), Cl (10.3 and 50.5 micro-g/g), Fe (29.3 and 202 ng/g), Mg (5.03 and 15.1 micro-g/g), Mn (29.8 and 199 ng/g), P (1.01 micro-g/g)(CRM 399), K (1.03 and 2.99 micro-g/g), Na (5.07 and 30.4 micro-g/g) and S (3.39 micro-g/g)(CRM 398). Indicative values (not certified) are given for P in CRM 398 and for S in CRM 399.
