Configuring HETP Report
When either the Full Report or the Calculated Values boxes are checked within the Report
Selections box, the Configure HETP button is enabled. The Configure HETP button opens
the HETP Report Configuration Screen. The user may then define the parameters for HETP
calculations, including the Start and End Points, Analysis Mode and HETP Variable.
Start and End Points
To select Start and End Points for the HETP data, click the appropriate button to choose either
Flagged Date Time (the start and end points of the selected run) or Manual Date Time (to input
start and end dates and times manually, in the Start and End Date Time boxes).
Analysis Mode
Select Pulse Analysis or Frontal Analysis by clicking the appropriate button. In Pulse Analysis,
the HETP peak data points are read directly from the historical data file. In Frontal Analysis, the
HETP peak data points are read from the absolute value of the derivative of the historical data.
When Frontal Analysis mode is selected, a smoothing algorithm is applied to the raw historical
data before the derivative of the data is calculated. The smoothing value is a moving average,
which appears in the Smoothing Index box. This may be adjusted using the scroll bar below the
box.
When Frontal Analysis mode is selected, the start point for calculating the derivative of the data
is defined as an offset from the start time. The length of this offset may be defined in the Base
Line Offset Time box, if Manual Date Time is selected.
HETP Variables
Four choices are available for the variable to be used for HETP calculations:
• AI201A post-column conductivity
• AI202 post-column pH
• AI203 post-column UV
• AI204 post-column UV
The chosen variable is selected by clicking on the appropriate button.
