N-Cyclohexylsulfamic acid sodium
Formula:C6H12NaNO3S
Mol. Welght:201.22
CAS No.:139-05-9
Storage Temperature:20℃±4℃
Storage and handling:The RM should be stored in the original sealed bottle at the temperature given above.After use the bottle should be tightly closed and protected from moisture.
Purity:99.82% (g/g)
Expanded Uncertainty U= 0.85% (g/g)
The uncertainty of this standard is calculated in accordance with the lSO Guide 34 and EURACHEM/CITAC Guide - Quantifying Uncertainty in Analytical Measurement, Second Edition.The expanded uncertainty is U(exp)=u(RM)x k, where k is the coverage factor at the 95% confidence level (k=2). Uncertainty u(RM)is based on the combination of the uncertainties associated with each indvidual operation involved in the analysis of the product u(RM)=vu(char)2+u(bb)2+u(lts)2+u(sts)2; u(char) is the uncertainty of charactersation; u(bb) uncertainty of homogeneity test;u(lts) uncertaintyof stability test long-term; u(sts) uncertainty of stablitytest short-term.u(lts) and u(sts) are not incuded in the calculation as the stablity statement is based on real evidence opposed to simulation.
Minimum sample: 1 mg is recommended as the minimal sample amount.If less material is used it is recommended to increase the ceritfied 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.
