1. A method for the impregnation of air with the vapour or aerosol of a substance in a repeatable and controlled manner to enable the testing or training of means for detecting to evaluate and quantify the presence of the substance in an enclosed volume in a real environment, comprising arranging for an airflow from said enclosed volume in said real environment to pass over a predetermined volume or predetermined surface area of the substance supported within a conduit having an inlet and an outlet for passage of the airflow at a predetermined flow rate for a predetermined period of time thereby impregnating air of said airflow with said vapour or aerosol of said substance in a repeatable and controlled manner, and further arranging for delivery of said impregnated air to said means for detecting the substance, wherein said real environment is the environment found at a real situation, as opposed to a simulated environment which is a fake or mock environment that seeks to emulate the characteristics of said real environment.
