In 1923, NPL’s Engineering Department was asked to improve the ventilation in the debating chamber of the House of Commons. Experiments were carried out at NPL on a 1/8 scale model and improvements recommended. The direction of air flow in the chamber was demonstrated by observing smoke produced by a special firework.
Today, NPL has world-class capability in the accurate production and analysis of gas reference materials to support a wide range of applications. We provide the underpinning measurement infrastructure via reference materials and state-of-the-art calibration techniques with unprecedented uncertainties. Our research has a direct impact on monitoring greenhouse gases, volatile organic compounds, vehicle emissions and breath alcohol. During the COVID-19 pandemic NPL used its expertise to study aerosol particles in dental surgeries which could carry the virus and impact air quality.
NPL uses the latest measurement techniques to inform industry, regulators and policy-makers on air quality.
