Abstract: A method for determining the flow rate of a gas includes measuring a first concentration of a calibration gas provided to the process chamber at a first pressure and temperature by directing infrared radiation into the process chamber and monitoring a first amount of infrared radiation absorbed by the calibration gas. A mixture of a second gas and the calibration gas is provided to the process chamber while maintaining the first pressure and temperature. A second concentration of the calibration gas in the mixture is measured by directing infrared radiation into the process chamber and monitoring a second amount of infrared radiation absorbed by the calibration gas. A flow rate of the second gas is calculated by comparing the first and second concentrations of the calibration gas. In one embodiment, the calibration gas and the second gas may not absorb the infrared radiation at the same wavelength.
