General tab

User Options - General

Show windows on the taskbar

All open windows can be displayed as icons on the taskbar or in the reverse case, it is possible to choose to have only the opened Instrument and the station's main Clarity window displayed on the taskbar.

Play sounds assigned to selected events

Permits sounds to be played with selected actions: Start, Stop, Abort, Snapshot, Open Chromatogram, Close Chromatogram. Other sounds can be selected on the Sounds tab of the Control Panels Windows dialog in the DataApex - Clarity section.

Send reports about unsuccessfully finished sessions

Allows the automatic delivery of a report which is used by DataApex technical support to troubleshoot the nature of the problem. A message box will automatically appear on the very next start-up after an error has occurred that has caused an improper shutdown of the system. This message box will inquire whether or not you would like to e-mail error information directly to the DataApex technical support.

Request confirmation when opening old file formats

When selected, while opening any file saved in a previous format the informative dialog will show up, saying that the file is in an obsolete format and will be converted to a new format upon saving. When not selected, the station will automatically convert all opened obsolete format files to the new one upon saving. When Save As command instead of Save command is used, the File Format combobox in the Save As dialog offers the obsolete format to be used, too.

Warn when maximum zoom reached

Activates/deactivates the warning message display when attempting to exceed the maximum zoom of the graph.

Warn before running already measured sequence

Activates/deactivates the warning message display when attempting to run already measured sequence.


Only the data from the last measurement of a given sequence may be reprocessed by the Batch command with Sequence Files parameter.

Ask whether create new subdirectory after single analysis

Enables/disables the confirmation message for creation of subdirectories after the single analysis measurement, if the subdirectory defined in the file name is not present. Similar feature is present in the Sequence measurements too, but the creation of the subdirectories is always silent.

Warn when reusing a Standard Chromatogram in Calibration

Activates/deactivates the warning message display when attempting to use already used Standard Chromatogram in a calibration.

Recent Files

Sets the number of recently opened files that will be displayed in the File menu. This setting is common to the Instrument, Sequence, Chromatogram and Calibration windows.

Mouse Wheel Step (in Graphs)

Sets the mouse wheel sensitivity on zooming the graphs.


Sets the general limits in Clarity.

"Chromatograms in Overlay"

Limits the number of chromatograms that can be simultaneously displayed in the Chromatogram window. The chromatogram displayed longest will be closed when the newer chromatogram is opened. 10,000 is the maximum number, the preset default is 20.

Injections in Sequence

Limits the maximum number of analyses measured from a single sequence. When the number of measurements reaches the set limit, the check of the sequence prevents from running it. This limit is set to prevent the lowering of the Clarity performance - sequence check may be unnecessarily long when there are several thousands of injections there.

Whole chromatograms are always counted regardless of the number of signals in the multi-detector chromatogram(s).

Counter (%n)

Allows for automatic reset of the %n counter used in the Single Analysis dialog. After checking, the counter will reset to 0 or 1 (according to further setting) at each Instrument window start.

The setting is common for one user, but the counter of each Instrument increases its value independently.


Similar setting for sequential measurement can be found in the Sequence Options dialog.

Table Fonts

Selects default fonts for all Clarity station tables.

Use Default Font

When selected, the station will use the font set by the Default Font… button in all tables. If the box is checked and filled with gray color (instead of black), it means that at least one column in one table contains a different font.

Default Font…

After clicking this button the Font dialog will appear where you may choose the font, style, color and size of the table text font.


If you wish to use a different font in any table, right click the mouse on the table and select the Setup Columns… command. This will open the Setup Columns dialog where it is necessary to deselect the Use Default Font checkbox in favor of desired font for specific column by using Font button.

Zoom Button

Selects which mouse button should be used for selection from the graph.

Left - It is the new standard. If you use the left mouse button, the right button will be used to open a local menu.

Right - As it was used in station CSW17.

Left Button Doubleclick Means

Defines what will occur when doubleclicking the left button in graph:

Unzoom - The graph returns to the appearance before zooming.

Set Signal to Active - If more chromatograms then one are displayed, doubleclicking over a specific chromatogram will set it as active.

Show Properties Dialog - Double-clicking on the graph opens the Graph Properties dialog for setting graph and chromatogram properties.

Chromatogram Cursors

Sets the cursor style for chromatogram modification. Cursor is shown as:

Only Vertical Line - A vertical line throughout the whole graph.

Arrows - Vertical line with two arrows at the point where this line intersects the chromatogram curve.

Animated Arrows - Animated arrows that function as those listed above.

Sequence Table - On Enter

Defines where will the focus move in Sequence table after pressing Enter.

Move Right - Default behaviour.

Move Down - Convenient to use with the barcode reader that emulates keyboard to fill in the Sequence table.
