Measurement according to normative specifications
In analytics, the compatibility of measurement results has central importance. Modern analysis methods are based on specifications and regulations that are laid out in national or international standards.
Standards in measuring technologies define the terms, measurement methods and the device of measuring. Standards also regulate interconnection by standardizing interfaces, communications and secure data transfer. They permit a qualitative approach to setting out standards as well as tolerances. While they are not legally binding, normative work is associated with high legal security for the users. It facilitates the selection of devices and ensures the quality of the in-house procedures and the quality of the product.
Polarimeters also are designed and used under the consideration of standards. Norms in the field of polarimetry define under the aspect of “best practice” the environmental conditions and sample preparation as well as measurement tolerances, properties and equipment of a device or calibration equipment. Using polarimeters in accordance to normative specifications can guarantee that the measurements are carried out correctly and in accordance to reproducible methods.
In order to make it easier for you to choose the right polarimeter for your application, you will find below an overview of all standards and guidelines that refer to polarimetry. This is a general overview of the standards. Which normative specifications the different polarimeter models from A.KRÜSS fulfil your requirements, we will be happy to discuss in a personal consultation. Please feel free to contact us.
