6.8.7. Dilution Ratio

The dilution ratio is a software option that allows the user to compensate for any dilution of the sample gas before it enters the sample inlet. Using the dilution ratio option is a 4-step process:

1.Select reporting range units: Follow the procedure in Section 6.8.6.

2.Select the range: Use the procedures in Sections 6.8.2 – 6.8.5. Make sure that the SPAN value entered is the maximum expected concentration of the undiluted calibration gas and that the span gas is either supplied through the same dilution inlet system as the sample gas or has an appropriately lower actual concentration. For example, with a dilution set to 100, a 10 ppm gas can be used to calibrate a 1000 ppm sample gas if the span gas is not routed through the dilution system. On the other hand, if a 1000 ppm span gas is used, it needs to pass through the same dilution steps as the sample gas.

3.Set the dilution factor as a gain (e.g., a value of 20 means 20 parts diluting gas and 1 part of sample gas):

The analyzer multiplies the measured gas concentrations with this dilution factor and displays the result.

Once the above settings have been entered, the instrument needs to be

recalibrated using one of the methods discussed in Section 7.
