2-1 Trace Oxygen Analyzer Operational Theory 2 Teledyne Analytical Instruments Operational Theory 2.1 Introduction The analyzer is composed of two subsystems: 1.
2-2 2 Operational Theory Model 3190 Teledyne Analytical Instruments stored within the cell, whereas in the Micro-Fuel Cell, one of the reactants (oxygen) 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.
2-3 Trace Oxygen Analyzer Operational Theory 2 Teledyne Analytical Instruments At the top end of the cell is a diffusion membrane of Teflon, whose thickness is very accurately controlled. Beneath the diffusion membrane lies the oxygen sensing element — the cathode — with a surface area almost 4 cm 2 .
2-4 2 Operational Theory Model 3190 Teledyne Analytical Instruments 2Pb + O 2 → 2PbO (These reactions will hold as long as no gaseous components capable of oxidizing lead — such as iodine, bromine, chlorine and fluorine — are present in the sample.
2-5 Trace Oxygen Analyzer Operational Theory 2 Teledyne Analytical Instruments Figure 2-2. Characteristic Input/Output Curve for a Micro-Fuel Cell 2.3 Electronics 2.3.1 General The signal processing uses an Intel microcontroller with on-board RAM and ROM to control all signal processing, input/output, and display functions for the analyzer.
2-6 2 Operational Theory Model 3190 Teledyne Analytical Instruments Figure 2-3: Block Diagram of the Signal Processing Electronics In the presence of oxygen the cell generates a current. A current to voltage amplifier (I – E AMPL) converts this current to a voltage.
3-1 Trace Oxygen Analyzer Installation 3 Teledyne Analytical Instruments Installation Installation of the analyzer includes: 1. Unpacking the system. 2. Mounting the Control Unit, External Sample Block, and Micro- Fuel Cell sensor. 3. Making the electrical connections.
3 Installation Model 3190 3-2 Teledyne Analytical Instruments shipped with all the materials you need to install and prepare the system for operation. CAUTION: Do not disturb the integrity of the cell package until the cell is to be used immediately.
3-3 Trace Oxygen Analyzer Installation 3 Teledyne Analytical Instruments For special applications the Micro-Fuel Cell may also be of a different type than the standard A-2C, B-2C or Z-2C unit. If this is the case, the pertinent cell specifications will be given in the addendum.
3 Installation Model 3190 3-4 Teledyne Analytical Instruments Figure 3-1 Rear Panel Electrical Connectors for AC and DC Units Primary Input Power (AC version): The power cord receptacle, fuse block and Power switch are located in the same assembly. A 6-foot, standard AC power cord is supplied with the Control Unit.
3-5 Trace Oxygen Analyzer Installation 3 Teledyne Analytical Instruments fuse receptacle, to the right of the power terminal strip, holds a 0.5 A, very quick acting fuse. (See Fuse Replacement in chapter 5, Maintenance .) The Power switch is located below the fuse receptacle.

Trace Oxygen Analyzer Operation 4 4-1 Teledyne Analytical Instruments Operation 4. 1 Introduction Once the analyzer has been mounted, the gas lines connected and the electrical connections made, the Analyzer can be configured for your appli- cation. This involves setting the system parameters: • Defining the user selectable analysis ranges.
4 Operation Model 3190 4-2 Teledyne Analytical Instruments Buttons When no buttons on the Analyzer are being pressed, the instrument is in the Analyze mode. It is monitoring the amount of oxygen in the sample gas that is flowing through the Remote Probe.
Trace Oxygen Analyzer Operation 4 4-3 Teledyne Analytical Instruments 4.3.1 HI Range Setting the HI Range fullscale value defines the LEAST sensitive analysis range to be used.
4 Operation Model 3190 4-4 Teledyne Analytical Instruments 2. Within 5 seconds, press either the ∆ or ∇ button to raise or lower the displayed value, as required, until the display reads the desired concentration. 4.4.2 LO Alarm Setting the LO Alarm sets the value BELOW which the LO alarm will activate.
Trace Oxygen Analyzer Operation 4 4-5 Teledyne Analytical Instruments Procedure: 1. Expose the sensor to ambient air or instrument grade air (20.9 % oxygen).
4 Operation Model 3190 4-6 Teledyne Analytical Instruments 4.8 “ SetL ” mode in the LED display When you turn on the unit, it displays “ 8.8.8.8 ” for a couple of seconds. This is to have an inspection that all segments of the display are all right.
5-1 Trace Oxygen Analyzer Maintenance 5 Teledyne Analytical Instruments Maintenance Aside from normal cleaning and checking for leaks, the Model 3190 should not require any maintenance beyond replacement of expended Micro- Fuel Cells, and perhaps a blown fuse.
5-2 5 Maintenance Model 3190 Teledyne Analytical Instruments open the spare fuse compartment, push on one end until it slides out. 4. Remove the blown fuse and replace it with a 5 × 20 mm 0.5 A, 250 VAC, IEC time lag (T) fuse (P/N F1128) for AC units.
5-3 Trace Oxygen Analyzer Maintenance 5 Teledyne Analytical Instruments CAUTION: Read the section Cell Warranty Conditions , below, before replacing the cell. CAUTION: After replacing the Micro-Fuel Cell, the analyzer must be recalibrated. See Calibration in chapter 4.
5-4 5 Maintenance Model 3190 Teledyne Analytical Instruments 3. Unscrew the cell-retainer cap from the cell block by turning it counterclockwise until it is free. Figure 5-2: Exploded View of MFC and Cell Block 4. Slowly withdraw the cap from the block.
5-5 Trace Oxygen Analyzer Maintenance 5 Teledyne Analytical Instruments 1. Disconnect the Power Source from the Control Unit. 2. Remove the new Micro-Fuel Cell from its protective bag. 3. Examine the O-ring at the base of the threaded portion of the cell- retainer cap, and replace it if it is worn of damaged.
