FTIR System

RAM System.png

The FTIR air monitoring system uses infrared light to detect gases.  The configuration for this technology is similar to the open-path TDL air monitoring system in that the beam of light is sent out in the open air to a reflector that sends the beam back along the same path.  The unit has the capability to detect total hydrocarbons and other organic gases on a real-time basis. The analytical method employed by the FTIR is a multiple regression technique that separates the total amount of light absorbance by the various gases and outputs a result for each gas. The system has the ability of undergoing data and quality assurance checks in the field by monitoring known ambient gases or by using gas standards.
