20. 60 ppm The reaction chamber is only in the system during gas phase titration This is because the reaction chamber is only needed during gas phase titration the flush time residence time is approximately less than one minute and three flush times are necessary for a response of 95 percent Gas flow through the oven is low approximately 150 sccm to stabilize the permeation tube oven temperature The major portion of the flow bypasses the oven and is directed to the mixing chamber with the stream from the oven This is achieved by using the same back pressure regulator described above for gas phase titration with a capillary of identical size Thermo Fisher Scientific Photometer Detector System Pressure Transducer Ozonator Ozonator Lamp Power Supply Photometer Lamp Power Supply Photometer Temperature Thermistor Pump Sample Reference Solenoid Valves Thermo Fisher Scientific System Description Flow System During standby operation a continuous flow of gas is necessary through the oven The standby flow and operating flow should be the same to 10 percent This is achieved by setting the pressure regulator to the same pressure setting as the back pressure regulator In practice rather than measuring the pressure it is the actual flows that are measured while adjusting the pressure regulator Two solenoids are used to change the flow of gas going through the oven to the main stream or to vent The photomet
