C H A P T E R Overview Th e ADInstruments ML206 Gas Analyzer is a set of transducers used for the measurement of respiratory gases. It contains infrared carbon dioxide and visible spectrum oxygen detectors, and connects to any PowerLab®...
Pick up the Gas Analyzer, tilt it gently from side to side, and listen for anything that appears to be loose. If you have found a problem, contact your authorized ADInstruments representative immediately, and describe the problem so arrangements can be made to replace or repair the unit.
If the internal fuses are suspected of having blown, the unit should be returned to your local ADInstruments representative. Status Indicator Th e Status indicator glows green when the Gas Analyzer is connected to a PowerLab and has been recognized by LabChart.

C Input and Output Ports Th e I C ports allow front-ends manufactured by ADInstruments to be chained together and supplied with power and communications from the PowerLab. Only 50 mA maximum current can be provided through this bus, so it should not be used for third-party devices drawing more current.
C H A P T E R Using the Gas Analyzer Th is chapter guides you through connecting your Gas Analyzer to your PowerLab and performing an initial check to make sure that there are no problems or omissions. IMPORTANT: Always turn off both the PowerLab and Gas Analyzer before connecting or disconnecting either unit.
PowerLab to the I2C Input connector on the back panel of the Gas Analyzer. You are able to use other ADInstruments front-ends at the same time as the Gas Analyzer by connecting them either before or aft er the Gas Analyzer in the I C chain.
Connecting to Other Recorders Analog signals from the Gas Analyzer are linear and proportional to CO and O partial pressures (CO output of 0–1 V is equivalent to 0–10% CO and O output of 0.05–1 V is equivalent to 5–100% O ).
It is also recommended that a PFT bacterial fi lter (available as part of the Spirometer Kit from ADInstruments, for example) be fi tted in the circuit aft er the face mask or mouthpiece so as to reduce bacterial build-up inside the Gas Analyzer.
Units… • Click the button to open the Units Conversion dialog, with which you can enter diff erent values for the channel, as described under “Calibrating with LabChart”, page 22; doing so deselects the Use default units checkbox. To revert to the default settings again, and so replace any previous settings made in the Units Conversion Use default units dialog, select the...

Default Calibration Settings Both transducers produce linear outputs that are directly proportional to the concentrations of the CO and O in the sample. Th e CO transducer has an output of 0–1 V for 0–10% CO and the O transducer has an output of 0.05–1 V for 5–100% O .

Details of how to use the extension can be found in the MP Calibration Guide that gets installed into the ADInstruments’ Documentation folder. Once the calibration values are entered and applied, they can be saved as a LabChart Settings fi le for later reuse.
C H A P T E R Care and Maintenance Th e Gas Analyzer has been designed to eliminate much of the usual maintenance associated with sensitive measuring devices. Th e only maintenance that you may need to perform is the replacement of the hydrophobic and bacterial fi lters.
Page 24
Th e only maintenance you should perform on the Gas Analyzer is the replacement of the external fi lters in the gas pathway. It is recommended that the unit be returned to your ADInstruments distributor annually for servicing. Note that removing the cover of the Gas Analyzer will void the warranty.
A P P E N D I X Technical Details Th is Appendix describes some technical aspects of the Gas Analyzer’s operation. You do not need to know the material in this section in order to operate the Gas Analyzer and it is not intended in any way as a service guide.
How it Works Th e Gas Analyzer has an infra-red transducer to measure CO concentration and a visible spectrum transducer to measure oxygen concentration. It has a response time of about 0.2 s (at ~200 ml/min) and can be used to indicate and O trends in exercising humans and small animals.
Considerations When Using the Gas Analyzer • Th e sample inlet and exhaust ports on the Gas Analyzer should remain clear. • Unnecessary dead-space in the gas path should be kept to a minimum. • Chemical contamination and rubber compounds should be avoided. •...

• Check that the power cable is fi rmly connected at the back of the Gas Analyzer. If the internal fuses are suspected of having blown, the unit should be returned to your ADInstruments distributor for servicing. Drift in the Output Signal Positive Drift : Contamination build up in the sample chambers of the transducers will cause a positive drift proportional to the build up.
