Reference Measurement Method

Reference measurement methods are analytical methods of the upper hierarchical level of metrology.

They enable the determination of target values of the highest accuracy and precision. Thus, reference method values come as close to the "true value" as is metrologically possible.

To achieve this highest level of accuracy of the measurement result, the reference laboratory of INSTAND uses special analytical methods such as mass spectrometry combined with gas chromatography (GC-MS), high-pressure liquid chromatography (HPLC-MS), or inductively coupled plasma (ICP-MS), and also photometric methods. For calibration, certified reference standards are used for the metrological traceability of the measurement result to SI units.
