  • Page 10: Introduction

    The Model 3110 incorporates a large standard feature list designed for versatile, accurate oxygen analysis for a wide range of applications. Figure 1-1 shows the standard Model 3110 Portable Trace Oxygen Analyzer.

  • Page 11: Features

    Portable Trace Oxygen Analyzer Introduction WARNING Though the 3110 can be applied to monitor percent oxygen, doing so will lead to more frequent sensor replacement requirements. Figure 1-1: Model 3110 Portable Trace Oxygen Analyzer 1.2 Features This instrument is designed to be a versatile analytical instrument and to perform reliably and accurately in analyzing oxygen concentrations in gas mixtures from the ppm level through 25% oxygen.
  • Page 12 • Real-time Clock: This feature allows the Model 3110 to date and time stamp the data set recorded on the data logger. It uses a 24 hour clock.

  • Page 13: Method Of Analysis

    1.4.1 Cell Warranty The Class B2-C, A2C, B2C-XL and Insta Trace micro-fuel cells can be used in the Model 3110 and are warranted for six (6) months from the date of shipment. With regard to spare cells, service time starts when the cell is removed from its shipping package.

    LED due to the power drain and low battery condition. At this point the unit should be removed from service and the batteries recharged. Figure 2-1: Model 3110 Rear Panel 2.2 Gas Connections The customer must provide a means of controlling the pressure and flow rate of the sample and zero gas.
  • Page 19 Do not place any valves or restrictions on the vent line except as noted above for atmospheric pressure sampling when using a downstream pump. Doing so would increase the sensor operating pressure and result in inaccurate analysis. Teledyne Analytical Instruments...

  • Page 20: Sensor Installation

    2.3 Sensor Installation The Model 3110's trace sensor requires that the instrument lines be immediately purged with zero gas after installing the cell. 2.3.1 Installing a Trace Sensor Prior to installing the trace sensor, make sure the analyzer is ready to purge with zero gas.

  • Page 21: Calibration

    120-135 ppm oxygen in nitrogen. 2.4.1 Calibration Procedure for Trace Analysis To calibrate the Model 3110, the instrument must be fitted with a trace sensor. The instrument must also be purged overnight using a zero gas (a pure gas with no oxygen, typically O free N ) before calibrating.

  • Page 22: Bleeding The Regulator And Purging The Gas Line

    Installation Model 3110 2.4.2 Bleeding the Regulator and Purging the Gas Line When using bottled gas (gas cylinder) as a calibration gas for trace analysis applications, the regulator and sample lines must be bled to remove traces of trapped air. Otherwise air that is trapped in the lines especially between the regulator and cylinder will result in a lengthening of the calibration time.

  • Page 23: External Signal

    0.1 V would represent 1 ppm, 0.2V would be 2 ppm; 0.3V would be 3 ppm etc. This output signal, when installed, is accessible from the rear panel. The output signal has an input impedance of 100Ω. Teledyne Analytical Instruments...

Routine maintenance consists of wiping down the instrument case, cleaning the screen and checking for leaks.

  • Page 41: Battery Power Supply Service

    4.4 Battery Power Supply Service The Model 3110 is designed to be intrinsically safe, and is designed for use only when not connected to the AC power line. TAI suggests that an overnight recharge be performed every few days for continuous use.

  • Page 42: Cell Replacement

    Maintenance Model 3110 Figure 4-1: Battery Charger Port on the Model 3110 4.5 Cell Replacement The characteristics of the micro-fuel cell are similar to those of a NiCad battery in that both provide an almost constant output through their useful life, and then fall off sharply towards zero at the end. If the sample being analyzed has a low oxygen concentration, cell failure will probably be indicated by the inability to properly calibrate the analyzer.

  • Page 43: Cell Warranty

    4.6 Cell Warranty The Class B-2C, A-2C, B-2CXL and Insta Trace micro-fuel cells used in the Model 3110 are warranted for six (6) months of service. With regard to spare cells, service time starts when the cell is removed from its oxygen barrier packaging. The customer should stock only one spare cell per instrument at a time.
