Trace Oxygen Analyzer Operational Theory 2 Operational Theory 2.1 Introduction The analyzer is composed of three subsystems: 1. Micro-Fuel Cell Sensor 2. Sample System 3. Electronic Signal Processing, Display and Control The sample system is designed to accept the sample gas and transport it through the analyzer without contaminating or altering the sample prior to analysis. The Micro-Fuel Cell is an electrochemical galvanic device that translates the amount of oxygen present in the sample into

2 Operational Theory Model 3000TA-XL-EU 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.) 2.2.2 Anatomy of a Micro-Fuel Cell The Micro-Fuel Cell is a cylinder only 1¼ inches in diameter and 1¼ inches thick. It is made of an extremely inert plastic, which can be placed confidently in practically any environment or s

The cathode has many perforations to ensure sufficient wetting of the upper surface with electrolyte, and it is plated with an inert metal. The anode structure is below the cathode. It is made of lead and has a proprietary design which is meant to maximize the amount of metal available for chemical reaction. At the rear of the cell, just below the anode structure, is a flexible

In the absence of oxygen, no current is generated. 2.2.4 The Effect of Pressure In order to state the amount of oxygen present in the sample in parts- per-million or a percentage of the gas mixture, it is necessary that the sample diffuse into the cell under constant pressure.

Depending on the mode of operation either sample or calibration gas is delivered. The Model 3000TA-XL sample system is designed and fabricated to ensure that the oxygen concentration of the gas is not altered as it travels through the sample system. The sample sy
