Abstract

Four mixtures of CO in N-2 and one of NO in N-2 were prepared for use as reference materials to verify the calibration gas mixtures used in particular in the analysis of exhaust gases produced by automobiles. Each batch of 100 cylinders was shown to be stable and homogeneous and 10 cylinders were analyzed by laboratories in Europe and by the NBS in the USA. The following levels are certified : CRM 313 : CO in N-2 : (4.483 +- 0.013) x 10**-2 mole/mole CRM 314 : CO in N-2 : (500.9 +- 1.5) x 10**-6 mole/mole CRM 315 : CO in N-2 : ( 50.2 +- 0.2) x 10**-6 mole/mole CRM 316 : CO in N-2 : ( 9.63 +- 0.03) x 10**-6 mole/mole CRM 317 : NO in N-2 : (95.7 +- 0.4) x 10**-6 mole/mole
