Description
To obtain timely data for the purpose of air quality assessment, air quality trend reporting, and to meet the requirements for inclusion of the data in provincial and national air quality databases, a continuous method of analyzing Non Methane Hydrocarbons (NMHC) concentrations in ambient air is used. This method is capable of measurement updates at a rate of once every five minutes or faster. Readings from instruments of this method enables the calculation of hourly averaged concentrations of Total Hydrocarbons THC, Methane CH4 and Non-methane Hydrocarbons NMHC. Commercially available NMHC analyzers are used in the method.
