Reference measurement procedures
Reference measurement procedures are analysis procedures of the highest hierarchical level of metrology. They enable target values to be determined with the highest level of accuracy and precision.
This means that the reference method values approximate the “true value” as close as technically possible. In order to achieve this high level of accuracy for the measuring results, special analytical methods are used in the INSTAND e.V reference lab, such as mass spectrometry combined with gas chromatography (GC-MS), high pressure liquid chromatography (HPLC-MS), inductively coupled plasma (ICP-MS) as well as photometric methods.
Certified reference standards are used during calibration to enable the metrological traceability of the measuring results to SI units.
The INSTAND e.V. calibration laboratory is accredited for the following analytes and reference measurement procedures.
