Storage and handling: The RM should be stored in the original sealed bottle at the temperatur given above.After use the bottle should be tightly cosed and protected from moisture and light.The expiny date is valid for original sealed botties under recommended storage conditions only.

Purity: 98.92%(/g) 
Expanded Uncertainty U= 0.30%(/g)

The uncertainty of this standard is calcuiated in accordance with the lS0 Guide 34andURACHEM/CITAC Guide-Quantifying Uncertainty in Analytical Measurement, Second Edition. The expanded uncertainty isU(exp)=u(RMxk wherek is the coverage factor at the 95% confidence leve(k=2).Uncertaintyu(RM) is based on the combination of the uncertainties associated with each individual peration involved in the analysis of the product:u(RM)=vu(char)2+u(bb+u(lts)2+u(sts)’;ufchar) is the uncertainty of purity determination;u(bb)uncertainty of homogeneity test; ufits) uncertainty of stability test long-term;u(sts)uncertainty of stabillty test short-term.ulits)andu(sts)are not included in the calculation as the stability statement is based on real evidence opposed to simulation.

Minimum sample:1 mg is recommended as the minimal sample amount.Iif 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.
