5.10.2 Universal Gas Run Commands
The three parameters and three check boxes on the left side of each stream tab refer to all of
the gas runs types for that particular stream:
• The Gain Factor is the parameter that relates the rate of stain on the tape to an actual
concentration. This value is determined during analyzer calibration with a known standard.
• The Zero Offset is the value that is subtracted from all concentration readings to give
corrected readings. Zero offset is obtained by running the ‘Zero’ stream, which is usually
run on a gas that contains no hydrogen sulfide, such as pure nitrogen.
• The Analysis Units field allows the user to change the units that are displayed on the
screen. This can be PPM, PPB, Mol%, or any other unit the user chooses. Changing the
value in this field does NOT change the calibration of the analyzer – if the user wishes to
change the calibration of the unit to be in a different unit, they must use a calibration gas
with a known concentration in the unit they wish to display.
• The Cal. Correction Enable check box is used to indicate that the calibration run is used to
change the gain factor. If this box is not checked, then the calibration run is essentially
another reference run.
• The Zero Correction Enable check box is used to indicate if the zero gas run to change the
zero offset. If this box is not checked off then the zero run is essentially another reference
run.
• The Timed Analysis Enable check box is used to indicate that the Peak Detect method of
analysis should be disabled and Timed Analysis method should be enabled. The method of
analysis used is determined by the application requirements and set at the factory.
5.10.3 The H2S and Total Sulfur Tab
The H2S and Total Sulfur tabs are used to enter relevant information about the analysis of
these gases. The tabs include the common gas run parameters described in Section 6.2.2
and the following parameters and settings.
5.10.3.1 Timing Commands
The Timing commands (Figure 5-21) relate to various timing issues and miscellaneous issues
that relate to operation of the system.
