A Chemtek Inc.(ACT) guarantees that the neat component has been fully characterized such as NMR,Mass as well as other reliable methods,andthe purity to be±0.5% deviation before the expiration date shown on the label and exclusive of any customer contamination. Gravimetric certification is based on the uncertainties of the balance and volumetric glassware used in the production.The uncrtainty calculated for this standardis±59%. The Uncertinty given is the expanded combined uncertainty and represents an estimated standard deviaion equal to the postive square rootof the total variance of the uncertainty of components. The expanded uncertainty is assumed with a coverage factor k=2 at a95%confidence level.Al1 measurements are traceable to SI Unit.
