Units Setup

Instrument units are set globally from this window only and affect gradient table, tabs of auxiliary pumps, monitors of auxiliary pumps, device monitor and tabs of other controlled devices in Method Setup and Chromatogram windows.

Basic Units and Auxiliary Signal Units can be set from the predefined. In case of the X-Axis Units, Custom Units are a possible choice.

Note:

Custom Units may result in incorrect calculations, since there is not a conversion table specified. Recommended for advanced users only.

X-Axis Units

Allows to set a different unit on the X-Axis than the default unit which is Time in minutes. Title can be changed to a custom value as well as the units. Once Custom unit is chosen Retention Time, Start Time and End Time columns of the Result Table can be renamed to a user defined value. Area, W05 and Drift columns of the Result Table will be displayed in Custom defined units.

Default

Upon clicking the Default button all units will be changed to the default units specified above.

Cancel

Cancels all changes made to the instrument units.

Note:

Chromatograms measured with custom defined units and then opened on Instrument with a default units set, will always display units according to the settings of the instrument.

Restrictions of the X-Axis Units:

  • X-Axis Units section is disabled (grayed out) for the following instrument types: LC-MS, GC-MS, GC-MS-ToF, GC-MS-PDA, DHA, NGA, GPC, GPC-PDA, EA and GCxGC.
  • Further settings of the X-Axis Units section apart from Custom option is allowed for CE and CE-PDA instrument types.
  • Full customization of X-Axis Units is allowed for LC, GC, LC-PDA and GC-PDA instrument types.
