| Abstract: | The words described the preparation method of reference material of gas, such as carbon monoxide, nitric oxide and propane in nitrogen,which were used for adapting the Europe standard of automobile exhaust, they also introduced the procedures of testing uniformity and stability of these gas reference materials by gas chromatography and NO-NO2-NOx analyzer to ensure testing data accuracy and reliability. The concentration of carbon monoxide and propane in nitrogen gas reference materials were both 1.00μmol/mol, the uncertainty was 3%. The concentration of nitric oxide in nitrogen was from 1.00 μmol/mol to 25.0 μmoL/mol,the uncertainty was 6%. |
| Keywords: | carbon monoxide propane nitric oxide reference material of gas weighing method uniformity stability |
