The principle of separation by CZE is to be stated. Concept introduction: The capillary zone electrophoresis is a type of electrophoresis in which separation of buffer solution takes place because of electrosoomotic flow. The buffer solution remains constant throughout the separation process. The rate of electrosoomotic flow controls the rate of migrating particles. The ionic compounds are easily separated by this method. The separation solution depends on the physical characteristics of the compound such as hydrodynamic radius, charge and ionic force of ions.

Question

Q3. A cellulose coating that weighs at least 3.00 mg is often applied to the exterior of vitamin C tablets in order to delay the release of active ingredients. A random sampling of 100 vitamin tablets revealed that 6 vitamin tablets failed to meet the required weight of the cellulose coating. (а) Calculate the relative standard deviation (in %). (b) Determine the number of tablets should be taken into consideration to ensure a relative standard deviation of 15 %.
