Gas Standards products & services
- The NPL Trace Gas Analysis Facility is capable of providing traceable measurements of the key contaminant species found in high-purity gases.
- Standard gas mixtures are an accurate and cost-effective method for calibrating air quality monitors. They are stable and provide a repeatable reference concentration that can be used for regular calibrations. They are suitable for calibrating all types of analyser (including flame photometric, UV fluorescence, chemiluminescence and optical UV or IR).
- Standard gas mixtures provide an accurate and cost-effective method for calibrating evidential breath-alcohol analysers. They are stable and provide a repeatable reference concentration that can be used for regular calibrations.
- Standard gas mixtures provide and accurate and cost-effective method for calibrating stack gas emission monitors. They are stable and provide a repeatable reference concentration that can be used for regular calibrations. They are suitable for calibrating all types of analyser (including non-dispersive infrared, flame photometric, UV fluorescence, chemiluminesence and optical UV or IR).
- Standard gas mixtures are an accurate and cost-effective method for calibrating vehicle exhaust monitors. They are stable and provide a repeatable reference concentration that can be used for regular calibrations.
- NPL provides primary reference natural gas mixtures (PRGMs) and liquefied petroleum gas standards for sale.
- NPL provides high-accuracy primary reference gas mixtures (PRGMs) for the analysis of a range of refinery gases (including coke oven gas, reformer gas, blast furnace gas, etc.).
