  • The certification of the contents (amount of substance contents) of ammonium, calcium, chloride, hydronium, magnesium, nitrate, potassium, sodium and sulphate in simulated rainwater : Low content CRM 408 : High content CRM 409


This report describes the preparation of two simulated rainwater reference materials (one with a low mineral content, CRM 408, the other with a high mineral content, CRM 409), the homogeneity and stability studies, as well as the analytical work for the certification of the contents of relevant species. The report contains all the results and the details of methods used to certify the amount of substance contents in CRM 408 and CRM 409 of, respectively, calcium (7.68 and 15.5 micro-mol/kg), chloride (67.3 and 113 micro-mol/kg), hydronium (16.6 and 48.0 micro-mol/kg), potassium (4.25 micro-mol/kg) (CRM 409), magnesium (6.14 and 12.3 micro-mol/kg), sodium (42.0 and 82.9 micro-mol/kg), ammonium (106 micro-mol/kg) (CRM 409), nitrate (20.1 and 78.1 micro-mol/kg) and sulphate (10.5 and 53.2 micro-mol/kg). Indicative values (not certified) are given for potassium and ammonium in CRM 408.
