Gas standards for olfactometry

Gas mixtures of compounds such as 1-butanol are regularly used for olfactometry testing applications. Examples of NPL's olfactometry gas standards are shown in the table below; other mixtures may be available on request.

Component Matrix gas Amount fraction range
From To
1-butanol Nitrogen or air 20 μmol/mol 100 μmol/mol
1-pentene Nitrogen or air 1 μmol/mol 80 μmol/mol
