  • Page 141: Theory Of Operation

    6. THEORY OF OPERATION The Model T400 ozone analyzer is a microprocessor-controlled analyzer that determines the concentration of Ozone (O ) in a sample gas drawn through the instrument.

    (Euler’s number) 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 T400, Ozone (O α is the absorption coefficient that tells how well O absorbs light at the specific wavelength of interest.

  • Page 143: The Photometer Uv Absorption Path

    HOTOMETER BSORPTION IIn 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 O and transparent to UV radiation at 254nm and into an absorption tube filled with Sample Gas.

  • Page 144: The Reference / Measurement Cycle

    O is present and when it is not. The Model T400 accomplishes this by alternately sending the sample gas directly to the absorption tube and passing it through a chemical scrubber that removes any O present.

  • Page 145: Interferent Rejection

    Measurement and Reference Phases rendering the analyzer useless for detecting O If the Model T400 is installed in an environment where the presence of mercury vapor is suspected, specific steps MUST be taken to remove the mercury vapor from the sample gas before it enters the analyzer.

  • Page 146: Sample Gas Air Flow

    6.2.1 S AMPLE The flow of sample gas through the T400 analyzer is produced by an internal pump that draws a small vacuum on the downstream side of a critical flow orifice thereby creating a controlled airflow through the analyzer’s absorption tube and other components. This requires the analyzer gas inlets be at or near ambient pressure usually managed by placing a vent line on the incoming gas line (see connections in Section 2.3.2).

  • Page 147: Particulate Filter

    ARTICULATE ILTER The T400 Ozone Analyzer comes equipped with a 47 mm diameter, Teflon, particulate filter with a 5 micron pore size. The filter is accessible through the front panel, which folds down to allow access, and should be changed according to the suggested maintenance schedule described in Table 5-1.

    The core of the analyzer is a microcomputer/central processing unit (CPU) that controls various internal processes, interprets data, makes calculations, and reports results using specialized firmware developed by Teledyne API.
