As a designated NMI, LGC is addressing the UK’s chemical and bio-measurement needs, which underpin the development and sustainability of the healthcare, food, environment, security and energy sectors. 

We are leading on the development of the UK bio-measurement system and its development internationally. We focus on high accuracy measurement research and calibration services as well as strengthening the traceability of measurements that underpin legislation, regulation and standardisation.
