ration of inorganic components in aqueous solutions based on gravimetric and spectral methods. The permissible certified values of the lead mass fraction in the developed IСP-CRM are shown to range from 800 mg/kg to 1200 mg/kg. The uncertainty in the certified value is expressed as expanded uncertai

Hans-Jürgen Elschenbroichhe oil content measurement error as compared to the first calibration option. Therefore, using natural oil for the calibration of NMR analyzers can considerably simplify the calibration process, reduce the calibration duration from 3–4 days to 3–4 h, as well as to exclude toxic solvents and addition
