K & Alpha

The K & Alpha dialog can be opened using the Load K & Alpha… button in the Single Analysis dialog, using the Sequence – Select K Alpha… command ( icon) in the Sequence window, or from the Common for All Signals section in the GPC Results tab of the Chromatogram window.

The dialog is used to define Mark–Houwink parameters (K and Alpha) for individual polymer/solvent/temperature combinations.

When opened from Single Analysis or Sequence, the dialog is used to select the appropriate K and Alpha values and transfer them to the measurement settings. When opened from the Chromatogram window, the dialog serves for reviewing or adjusting the values for the active chromatogram only.

When a non-universal Narrow calibration is used (standards and unknowns of the same polymer), the K and Alpha parameters are not applied to the calibration curve or molecular weight results. In such cases, the values may remain at their default placeholder settings.

K & Alpha

The table lists available parameter sets including Polymer, Solvent, Temperature, K and Alpha values, and optional Remark.

OK

Confirms the selection of the highlighted row and closes the dialog.

If the dialog was opened from the Single Analysis dialog or the Sequence window, the selected K and Alpha values are applied to the respective measurement settings.

If the dialog was opened from the Chromatogram window (via the Common for All Signals section), the selected values are not applied to the active chromatogram. If needed, they must be adjusted there manually.

Cancel

Closes the dialog without applying any changes.
