Abstract
A method for analyzing a gas sample includes the steps of providing a gas sample to a sample canister and heating a sensor to a predetermined resistance. The method further includes the steps of operating a fan at a predetermined speed, and moving a valve to a measurement flow position. When the valve is in the measurement flow position, the fan draws a portion of the gas sample through the valve to expose the sensor to the gas sample.
