Compound Name: Chioroparaffin C10-C13 55,5%C

Lot. No.: 106018

Purity: 100.0%

Weight: 200.005 mg 
Batch Soivent: Cyciohexane

Solvent Lot: 1093411736

Batch size: 2000.00 ml 
Concentration: 100.00 mg/l

Expanded Uncertainty U: 2.09mg/l

The uncertainty of this standard is calculated in accordance with the ISO 17034 and URACHEM/CTAC Gulde-Quantifving Uncertainty in Analytical Measurement,Second Edition.The expanded uncertainty is U(exp)= u(RM) xk where k is the coverase factor at the 95% confidence level (k=2).Uncertainty u(RM) is based on the combination of the uncertaintiles assocated with each individual 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 characterisation;ubb)uncertainty of homogeneity test;u(lts)uncertainty of stability test long-term；u(sts) uncertainty of stability test short-term.u(lts) and u(sts) are not included in the calculation as the stability statement is based on real evidence opposed to simulation.
Minimum samole: 1 ml is recommended as the minimal samole amount.ifless material is used.itis recommended to increase the certified uncertainty by a factor of two for hatf 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
