8.3.12 Gas Concentration Calculator
This feature is not available in Setup Tool. The Gas Concentration
Calculator contains two separate utilities. One calculator allows off line
calculations of concentration given two reference frequencies and the other
calculator estimates concentration from vapor pressure and flow parameters.
See Figure 8-12. Select the carrier and reactant gases from the drop down lists.
Enter the resonant frequency of the pure carrier and the resonant frequency of
the carrier (depends on cell temperature) and precursor mixed gas. Press the
associated Calculate button and the concentration will be calculated and
displayed.
On the other hand, enter the appropriate flow and pressure parameters. Press
the associated Calculate button and the concentration will be calculated and
displayed, assuming constant pickup efficiency of the carrier gas.
