Column Tag Information (Integrated Column Compartment Column Assignment)

The table shows the information stored on the RFID tag(s) of the installed column(s). The active (currently selected) column is highlighted.

By default, only the columns up to and including Injections are shown; click >> at the top right of the table to show the full table, and << to show the reduced table.

The characters ; (semicolon),' (single quote) and " (double quote) are invalid for the Column Tag Information table. If these characters are used in any field of the table, an error is displayed and OK/Write Tag is disabled. You must delete all invalid characters before you can write the data to the tag.

The information is provided for documentation purposes only. Be aware that the values are not used to validate your current method parameters (for example, maximum pressure settings).

Refresh Table

The data in the table is replaced by the values from the instrument. This applies to all tags in the system.

OK/Write Tag

If changes are detected, the Column Tags Changed dialog box is displayed to allow you to choose what to do:

  • refresh the content of the table from the content of the current tag

  • write the current content of the table to all tags

  • exit the dialog box without changing the content of the table or the tags

Column Tag Context Menu

Clear Column Tag Information

Clears all fields in the selected row of the table.

For a tag that is physically present, the values for Injection and First Injection are not cleared. These values are cleared only if they are stored in the module.

Seal Column Tag

All fields except Comment and Void Volume will be set irrevocably to read-only.

Copy

Copies the contents of the selected row (except the Location and Color Code fields) to the clipboard.

Paste

Pastes the contents of the clipboard into the selected row (except the Location and Color Code fields).

The changes to the column tag information are written only when you leave the Column Assignment dialog box by clicking OK/Write Tag. If you leave the Column Assignment dialog box by clicking Cancel, all changes (including Seal Column Tag) are discarded.
