Nonylphenol (technical)

Formula：C15H24O

Mol. Welght：220.35

CAS No.：25154-52-3

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：99.90% (g/g)

Expanded Uncertainty U= 2.00% (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.
