Comparison of NO in N2 (600 to 850 10-9 mol/mol) expressed in amount fraction units
Project Description
As a follow up of key-comparison CCQM-26a JRC and NPL will carry out a bilateral comparison on NO in N2 measurement at ambient concentrations.
The project will compare the JRC value, calibrated by the static dilution technique, to the gravimetric reference value of NPL.
