Abstract
An infrared beam is applied into an infrared transmitting substrate disposed in an environment to be measured; the infrared beam which has undergone multiple internal reflections in the infrared transmitting substrate and exited from the infrared transmitting substrate is detected; the detected infrared beam is spectroscopically analyzed to measure a species and/or a quantity of the substance in the environment present near the infrared transmitting substrate ; and a species and/or a concentration of the substance in the environment to be measured are measured based on the species and/or the quantity of the substance in the environment present near the infrared transmitting substrate . Thus, the substances in the environment, such as organic contaminants, etc., present in the atmosphere can be identified, or their concentrations can be measured, with high sensitivity and realtime.
