Sample Diluter Maintenance - Teledyne 6200A Manual

4.4 Sample Diluter Maintenance

The sample diluter is used to inject a small amount of ambient air into the sample stream to provide
oxygen for the converter. The diluter is located on the inside rear panel of the SO2 analyzer. It consists of
a stainless steel block and 2 orifices to control the amount of sample and air that is blended.
There should be no periodic maintenance required on this assembly, but a diagram is included in case
rebuilding of this assembly is required. The assembly is shown in Figure 4.1.
If no drop off occurs when the temperature is raised to 1050C, select the set-point
temperature that maximizes analyzer reading.
