1. A method of measuring the concentration of a target gaseous or aerosolized compound in a gaseous environment, the method including the steps of:
extracting a selected sample quantity of the gaseous environment into a target gas measurement system;
separating the target gaseous or aerosolized compound from the quantity of sample gas, into a store;
sensing, with a target gas sensor, the amount or concentration of the target gaseous or aerosolized compound from the store,
sensing with a gas sensor, at least one second gas component selected from the group consisting of oxygen, carbon dioxide, carbon monoxide, and volatile organic compounds;
receiving in a processor, data from the target gas sensor relating to the amount or concentration of the target gaseous or aerosolized compound;
converting, in the processor, the target gas sensor data, with a conversion algorithm, to obtain environmental concentration data of the target gaseous or aerosolized compound by adjusting the concentration data with reference to a target sensor sensitivity to the at least one second gas component; and
storing in a data store or displaying on a display, the environmental concentration data, or transmitting the environmental concentration data to a remote server or processor.
