Abstract
This paper presents information on the development and certification of reference materials (CRM) for the composition of aqueous aluminium, indium, magnesium, nickel and titanium solutions. CRMs are represented by aqueous solutions containing aluminium, indium, magnesium, nickel and titanium ions. CRMs have been packed into 5, 10 and 25 cm3 glass ampoules, as well as into 50 and 250 cm3 polypropylene vessels. The certified values of metal mass concentrations were established according to the preparation method. The certified value of the mass concentration of metal ions in the CRMs under study is found to vary within the range of 0.95–1.06 g/dm3. Both the relative expanded uncertainty (under k = 2) of the certified mass concentration and the relative standard uncertainty due to instability do not exceed the values of 0.8% and 0.069%, respectively. The developed CRMs are shown to have the shelf life of 3 years provided that standard storage conditions are ensured. The developed CRMs are included into the RF State Register of Certified Reference Materials under the following numbers: CRM 11122-2018, CRM 11123-2018, CRM 11124-2018, CRM 11125-2018 and CRM 11126-2018. The CRMs produced by the All-Russian Scientific Research Institute for Optical and Physical Measurements (VNIIOFI) are characterized by the values of expanded uncertainty comparable to those of world leaders in the production of similar materials.
