2-1 Ultra Trace Oxygen Analyzer Operational Theory 2 Teledyne Analytical Instruments Operational Theory 2. 1 Introduction The analyzer is composed of three subsystems: 1.
2-2 2 Operational Theory Model Ultra Trace 3000 Teledyne Analytical Instruments comes from outside the device as a constituent of the sample gas being analyzed. The Micro-Fuel Cell is therefore a hybrid between a battery and a true fuel cell. (All of the reactants are stored externally in a true fuel cell.
2-3 Ultra Trace Oxygen Analyzer Operational Theory 2 Teledyne Analytical Instruments the oxygen sensing element — the cathode — with a surface area almost 4 cm 2 . The cathode has many perforations to ensure sufficient wetting of the upper surface with electrolyte, and it is plated with an inert metal.
2-4 2 Operational Theory Model Ultra Trace 3000 Teledyne Analytical Instruments (These reactions are specific to oxygen as long as no gaseous components capable of oxidizing lead — such as iodine, bromine, chlorine and fluorine — are present in the sample.
2-5 Ultra Trace Oxygen Analyzer Operational Theory 2 Teledyne Analytical Instruments temperature minimizes the cell offset (typically less than 75 PPB). A second benefit of the TEC system is that by regulating the cell temperature the analyzer becomes tolerant of thermal transients.
2-6 2 Operational Theory Model Ultra Trace 3000 Teledyne Analytical Instruments 2 . 3 Sample System The sample system delivers gases to the Micro-Fuel Cell sensor from the analyzer rear panel inlet. Depending on the mode of operation either sample or calibration gas is delivered.
