Acetone C3H6O 67-64-1 41041345 The maximum uncertainty in the preparation of this Custom Organic Standard is ±5% a All weights are traceable through National Institute of Standards and Technology, Test No.822/254480 b The concentration, in mg/l units, were obtained by multiplying the certified value by the measured density of the Custom Organics Standard solution at 19.30C (0.78966 g/ml) Preparation and Analysis - This Organic solution was prepared by weighing and mixing the individual substance and Acetone . The weighed components were added to the Acetone and mixed until completely dissolved and homogenized. When it is not possible to perform a simple weighting procedure, the individual component is disolved into a proper solvent to a certain concentration.10 ml aliquots of this bulk solution were dispensed into sealed glass ampoule 10 ml . All processes (including generating of this certificate) are completely controlled by the specialized Computer-Aided-Manufacturing (CAM) software.
