13. THEORY OF OPERATION The Model T400 ozone analyzer is a microprocessor-controlled analyzer that determines the concentration of Ozone (O3) in a sample gas drawn through the instrument. It requires that sample and calibration gasses be supplied at ambient atmospheric pressure in order to establish a stable gas flow through the absorption tube where the gas’ ability to absorb ultraviolet (UV) radiation of a certain wavelength (in this case 254 nm) is measured.
Theory of Operation T400 Ozone Analyzer Operator’s Manual L C is the absorption path, or the distance the light travels as it is being absorbed. is the concentration of the absorbing gas. In the case of the Model T400, Ozone (O3). is the absorption coefficient that tells how well O3 absorbs light at the specific wavelength of interest.
T400 Ozone Analyzer Operator’s Manual Theory of Operation 13.1.2. THE PHOTOMETER UV ABSORPTION PATH In the most basic terms, the photometer of the Model T400 uses a high energy, mercury vapor lamp to generate a beam of UV light. This beam passes through a window of material specifically chosen to be both non-reactive to O3 and transparent to UV radiation at 254nm and into an absorption tube filled with Sample Gas.
Theory of Operation T400 Ozone Analyzer Operator’s Manual 13.1.3. THE REFERENCE / MEASUREMENT CYCLE ABSORPTION TUBE In order to solve the Beer-Lambert equation (see Section 10.1.2) it is necessary to know the intensity of the light passing through the absorption path both when O3 is present and when it is not. The Model T400 accomplishes this be alternately sending the sample gas directly to the absorption tube and passing it through a chemical Scrubber that removes any O3 present.
T400 Ozone Analyzer Operator’s Manual Theory of Operation 13.1.4. INTERFERENT REJECTION The detection of O3 is subject to interference from a number of sources including, SO2, NO2, NO, H2O, aromatic hydrocarbons such as meta-xylene and mercury vapor. The Model T400’s basic method or operation successfully rejects interference from most of these Interferents. The O3 scrubber located on the reference path (see Figure 13-2) is specifically designed ONLY to remove O3 from the sample gas.
Theory of Operation T400 Ozone Analyzer Operator’s Manual 13.2. PNEUMATIC OPERATION Note It is important that the sample airflow system is both leak tight and not pressurized over ambient pressure. Regular leak checks should be performed on the analyzer as described in the maintenance schedule, Table 11-1. Procedures for correctly performing leak checks can be found in Section 11.3.4. 13.2.1.
T400 Ozone Analyzer Operator’s Manual Theory of Operation 13.2.2. FLOW RATE CONTROL To maintain a constant flow rate of the sample gas through the instrument, the Model T400 uses a special flow control assembly located downstream from the absorption tube and in the exhaust gas line just before the pump (see Figure 10-7). This assembly consists of: A critical flow orifice.
