This is a gas mixture containing nitrogen oxide (NO) in a range of concentrations, typically used in the environmental and automotive fields. It is used for air quality monitoring as a calibration gas mixture for the gas chromatographs fitted in control units operated by environmental control bodies, and in the automotive world for the analysis of exhaust gases during engine emissions testing.

This gas mixture is available in lightweight aluminum alloy cylinders in a range of capacities, from 5 liters to 50 liters.

The mixture is calibrated or produced in accordance with preparation and analysis procedures accredited by ACCREDIA and is therefore metrologically valid.
