Reference measurements and materials

Traceable measurements with known uncertainties are essential to standardisation:

  • to compare measurement results between different testing laboratories.
  • to support manufacturing and product development i.e. product measured property(ies) compared to product and manufacturing specifications.
  • to help industry comply with regulatory and legislative requirements i.e. measured sample property(ies) compared to legislative and regulatory limits.

Reference measurements

Within the NML at LGC, we perform high accuracy chemical (organic and inorganic) and bio-measurements (DNA), offering our customers measurements they can trust, with known uncertainties and full traceability to recognised international standards.

Our reference measurements are provided using our in-house methods, accredited to ISO17025 (calibration and testing).

In chemical analysis, higher accuracy and traceability are achieved using isotope dilution mass spectrometry (IDMS). Using our flexible scope protocols, we can provide IDMS (traceable) measurements with known uncertainties for a wide range of analytes and matrices e.g. food, environment and clinical. The details of those measurements can be found below.

Reference Materials

Within the NML at LGC, we develop and produce reference materials that underpin complex measurements.

Many of the analytical methods used to characterise our reference materials are accredited to ISO/IEC 17025 and have been verified through participation in key comparison studies organised by the Consultative Committee for the Amount of Substance (CCQM) of the International Weights and Measures Organisation (BIPM)

Our reference material production is accredited to ISO 17034.

Our reference materials can be purchased through the LGC Standards Webshop.
