The calculation begins by flashing the lamp 10 times per second After the lamp flash a sample and hold circuit on the input board is used to sample the PMT output The raw accumulated counts are scaled according to the gain setting of the input board Next the uncorrected values are determined according to a unique averaging algorithm which minimizes errors resulting from rapidly changing gas concentrations This algorithm results in values which are stored in RAM in a circular buffer that holds all the ten second data from the previous five minutes This data is averaged over the selected time interval which can be any multiple of ten between 1 and 300 seconds The background values which are corrected for temperature are subtracted from their respective averages The reading is corrected by the stored span factor and by the temperature factor The front panel display serial and Ethernet data ports and analog outputs are the means of communicating the results of the above calculations The front panel display presents the SO concentrations The display is updated every 1 10 seconds depending on the averaging time The analog output ranges are user selectable via software The analog outputs are defaulted based on the measurement range The defaults are Model 43i Instruction Manual 8 5 System Description Electronics Electronics Motherboard External Connectors Internal Connectors 8 6 Model 43i Instruction Manual

SO molecules The condensing lens focuses the pulsating UV light into the mirror assembly The mirror assembly contains four selective mirrors that reflect only the wavelengths which excite SO molecules As the excited SO2 molecules decay to lower energy states they emit UV light that is proportional to the SO2 concentration The bandpass filter allows only the wavelengths emitted by the excited SO2 molecules to reach the photomultiplier tube PMT The PMT detects the UV light emission from the decaying SO2 molecules The photodetector located at the back of the fluorescence chamber continuously monitors the pulsating UV light source and is connected to a circuit that compensates for fluctuations in the UV light As the sample leaves the optical chamber it passes through a flow sensor a capillary and the shell side of the hydrocarbon kicker The sample then flows to the pump and is exhausted out the EXHAUST bulkhead of the analyzer The Model 437 outputs the SO concentration to the front panel display and the analog outputs and also makes the data available over the serial or Ethernet connection Thermo Fisher Scientific Introduction Specifications 1 l z Pass Electronics a A s Flashlamp F E id Te LIIN D A yo E ne SA Photodetector wr TON A AFAN gt Hydrocarbon y Kick
