5.4 Taking a Gas Sample for<br />
Analysis<br />
For Sentrum to accurately track the<br />
fluctuating methane concentration in the<br />
gas transport pipe, it needs to acquire<br />
knowledge about the “Gas Signature” of the<br />
installation. This information is derived from<br />
gas chromatograph analysis of a gas sample<br />
collected from the installation.<br />
To collect a sample of gas for analysis the<br />
following procedure must be followed:<br />
1. Physically extract the sample of gas from<br />
the main line extraction point.<br />
2. Then enter the MDM Setup menu and<br />
confirm that the sample has been taken.<br />
3. Selecting and confirming the Sample<br />
Taken option will save the uncorrected<br />
methane sensor output with the<br />
corresponding time and date. This<br />
information is used by the controller to<br />
calibrate the correction factors once the<br />
results of the analysis are available.<br />
4. Information about the last sample taken<br />
can be viewed by selecting the View<br />
Sample option.<br />
