311XL SERIES

TRACE OXYGEN ANALYZER

1.INTRODUCTION

1.1Description: The Teledyne Analytical Instruments (TAI) Model 311XL and 311TCXL are portable, intrinsically safe trace oxygen analyzer which can be operated without an external power source. These analyzers will be referred to as Model 311XL or 311XL Series analyzers in this manual.

The instrument provides for trace oxygen analysis in decade steps ranging from 0-2 to 0-10,000 ppm (full scale) plus a special calibration range that encompasses the known oxygen concentration of atmospheric air (209,000 ppm).

Sample oxygen is read from an extremely accurate integral meter whose range of measurement is determined by the position of the range selector switch. The linear 5 inch scale (mirror equipped to eliminate parallax) provides excellent resolution and accuracy.

Sample gas is introduced and vented via a pair of quick disconnect fittings that feature integral shutoff valves which automatically close when the mating male fitting is withdrawn. The fittings are an integral part of the measuring cell manifold so that internal sample passage volume is at an absolute minimum. Sample flow control of 0.5 to 5 liters/min. must be accomplished with accessory equipment.

1.2Method of Analysis. The sample oxygen is measured by a unique electrochemical transducer which functions as a fuel cell. Oxygen diffusing into the cell reacts electro-chemically to produce an electrical current that is proportional to the oxygen concentration in the gas phase immediately adjacent to the transducer’s sensing surface. The linear, but minute, signal produced by the transducer from trace oxygen is amplified by a two stage amplifier. The dual stages of amplification provide enough gain to drive meter and thermistor controlled network utilized to compensate for the positive temperature co-efficient of the transducer.

1.3Outstanding Features. The following unique features are incorporated into the Model 311XL:

1.3.1Micro-Fuel Cell: The Micro-Fuel Cell* is a sealed electrochemical trans- ducer with no electrolyte to change or electrodes to clean. When the cell reaches the end of its useful life, it is merely thrown away and replaced, as one would replace a worn out battery in a flashlight.
