C9-alkylbenzenes mass concentration
in scheme: ACTRIS Vocabulary
Observation Matrix: gas phase
definition: Mass concentration means mass per unit volume and is used in the construction mass_concentration_of_X_in_Y, where X is a material constituent of Y. A chemical species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. C9-alkylbenzenes are aromatics with 9 carbons, including the benzene ring (2 propylbenzenes, 3 ethyltoluenes, 3 trimethylbenzenes)
