Teledyneʼs patented* innovation
called INSTA TRACE ™ eliminates
the greatest inconvenience
associated with electrochemical oxygen
sensors at the trace level - the wait.
When a typical electrochemical trace
oxygen sensor is removed from its barrier
bag for the purpose of replacing an
expired sensor, it is exposed to ambient air

(209,000 ppm O2).

• No waiting
• No diverting product
• No switching analyzers
• No liquid backup

During this transition from an oxygen free environment to open air exposure, the sensorʼs electrolyte
becomes saturated with dissolved oxygen – and the longer the exposure, the longer the recovery time.
The typical recovery period when replacing a sensor is between 6 to 24 hours.
The INSTA TRACE Micro-fuel Cell oxygen sensor is capable of measuring below 1 ppm of oxygen
within 15 minutes of installation. By reducing the recovery period from several hours to just minutes,
users will no longer have to divert unanalyzed product, go to liquid back-up (in the case of the air
separation industry), or switch analyzers. The intrinsic value of this innovation has extreme significance
in plant operation.

Using Teledyneʼs Insta Trace
technology, meaningful readings
below 1 ppm are obtained in only
15 minutes.

HOW IT’S DONE
The solution Teledyne engineered to address this recovery concern is simple yet extremely effective. By covering
the base of the sensor with a seal, the cell is protected from exposure to ambient air. Insertion in the newly designed
cell holder rests the INSTA TRACE sensor against a prong. As the cell holder is closed, the prong punctures the seal
thereby allowing the fl ow of gas to the cathode to begin in a controlled setting. The new cell holder is designed to
ensure the prong will not come in contact with the actual reactive sensing surface of the sensor.

WHERE INSTA TRACE CAN BE APPLIED
Teledyne can retrofi t INSTA TRACE sensing capability into all of its Micro-fuel Cell based trace oxygen analyzers
currently in service. The retrofi t kit contains the cell holder in addition to the INSTA TRACE sensor. Simply replace the
old cell holder (the bottom piece that either threads or mechanically clamps to the cell block assembly) and install the
INSTA TRACE sensor. Take advantage of this innovation by ordering the appropriate retrofi t kit.
