Preparation of Standards – Easier than Ever with the Sartorius Cubis® MSA Dosing System - 1

Application Note June, 2017 Keywords or phrases: Preparation of standards or solutions of defined concentration for analytical procedures Preparation of Standards – Easier than Ever with the Sartorius Cubis® MSA Dosing System Holger Densow* Sartorius Lab Instruments GmbH & Co. KG, Otto-Brenner Str. 20, 37079 Göttingen, Germany * Correspondence E-Mail: holger.densow@sartorius.com Abstract Preparation of standards, also called reference samples, of known concentrations is a common routine procedure in analytical laboratories. Internal or external standards with very low concentrations are used in these laboratories for highly sensitive quantitative analytical methods to exactly determine the concentration of chemical components in samples using highly sensitive quantitative analytical procedures.

Preparation of Standards – Easier than Ever with the Sartorius Cubis® MSA Dosing System - 2

Preparation of standards of known concentrations is a common routine procedure in analytical laboratories. Internal or external standards with very low concentrations are used in these laboratories for highly sensitive quantitative analytical methods to exactly determine the concentration of chemical compounds in samples. External standards are separate samples used for comparison to test samples, whereas internal standards are added to the samples to be analyzed. Therefore, the concentration of such standards must be as accurate as possible to prevent subsequent errors in the determination...

Preparation of Standards – Easier than Ever with the Sartorius Cubis® MSA Dosing System - 3

Compared with known, fully automatic dispensing systems on the market, the product presented in this Application Note offers a number of decisive advantages. Fully automatic systems, which take care of dispensing fine powder, granules and homogeneous or heterogeneous mixtures, require exact knowledge of the dispensing properties of these substances. For example, the flowability, size, shape, compactness, density, tendency to aggregate and electrostatic properties of the particles must either be known or visually evaluated. Choosing the right dispensing head is not always easy given the many...
