4-28 | Model 933S UV Analyzer
‘**’ following the parameter names below indicates the parameter
should only be modified by a trained technician.
Cell Length**
The axial length of the Measuring Cell gas space (cm).
Default Cell Temp
The Measuring Cell (°C) default temperature. This value is used in
place of the Measuring Cell temperature when measured temperature
compensation is disabled.
Compressibility Correct Factor
In addition to pressure and temperature compensations of the concen-
trations according to the ideal gas law, it is possible to enter an ad-
ditional parameter (Z) to account for the compressibility factor of the
sample gas. One value of Z is used for all species. The default value for
this parameter is ‘1’, but can be any value between ‘0.5’ and ‘1.5’. The
correction is applied to the concentrations in the following manner:
<Conc>
corr.
= <Conc>
uncorr.
/ Z
Cell/Miscellaneous (Compensations) Parameters
The Cell/Misc Parameters dialog box contains compensation parameters
used to calculate the concentration, plus other miscellaneous parameters.
They account for temperature, pressure, compressibility, and other varia-
tions that affect the concentration reading computed by the analyzer.
