ABSTRACT:
The method and apparatus of this disclosure are directed to a system for diluting a sample gas. For example, the sample gas may carry excessive water which creates difficulties in analysis. The apparatus includes an inlet line, a control valve which switches through several positions to provide 1, 2 or 3 decades of dilutions and each decade is defined by a flow through a restricted orifice calibrated to a specified flow volume. The sample is diluted with the dilution flow which is furnished through a similar orifice, but that orifice is replicated in a ratio of N:1. The N orifices provide the cumulative dilution flow which is commingle with the sample. Two more decades can be switched to obtain a wide range of dilution.
