Storage and handling: The M should be stored in the original sealed bottleat thetemperature given above.After use the bottle should be tightly closed and protected from moisture
Purity: 99.22%(g/g)
Expanded Uncertainty U= 0.54%(g/g)
The uncertainty of this standard is calculated in accordance with the ISO Guide 34and EURACHEM/CITAC Guide-Quantifying Uncertainty in Analytical Measurement.Second Edition.The expanded uncertainty is U(exp)=u(RM)xk,wherekis the coverage factor at the 95% confidence level(k=2).Uncertainty u(RM) is based on the combination of the uncertainties associated with each individual operation nvolved in the analysis of the product:u(RM)=Vu(char)2+u(bb)²+u(lts)² +u(sts)2；u(char) is the uncertaintv of characterisation:ubb)uncertainty of homogeneity test:utsuncertainty of stability test long-term; usts) uncertaint of stability test short-term.u(lts)and u(sts)are not included in the caculation as the stability statement is based on real evidence opposed to simulation. Minimum sample: 1mg is recommended as the minimal sample amount.If less material is used,it is recommended to increase the certified uncertainty by a factor of two for half sample and a factor of four for a quarter of sample.
Intended use: Use this RM as calibrant for chromatography or any other analytical technique.
