2.3 Sample Conditioning System
The sample-conditioning system ensures a clean, regulated sample for the analyzer. Sample-gas
composition and pressure, along with other factors, may require modifying the conditioning system
for a specific application. Mount the sample-conditioning system below the analyzer if possible. The
typical system may consist of a sample probe, drip pot, one or two regulators, and a membrane filter.
Some samples require an additional pressure regulator at the sample tap. One to three pressure drops
may be necessary to ensure that the analyzer receives a sample that is free of liquids. A typical system
is illustrated below.
NOTE: Configuration may be different pending the analyzer ordered.
