System Suitability Testing (SST)


SST tracks are defined in the Sample Sequence, column SST.

In this tab, you can define and validate SST.


SST Table

It is the definition of the tests, e.g. which substance should be at which Rf (and with a specific Rf window).

  • addsubstance Add a new substance row

  • deletesubstance Delete the selected substance row


Here you can select the illumination or wavelength of a specific HPTLC step you want to view. Clean plate data acquisition steps are not shown. For Visualizer steps, the profiles must be generated by using the Generate Profiles function in the analysis’ Data tab.

SST View

In this section, the profile (on the left side) and the pseudo track (right side) is displayed for each track defined as SST, at the selected illumination/wavelength. In the middle, each substance is positioned relatively to its Rf and Rf window defined in the SST Table. You can check a substance to define it as Passed.

The main display has the following options:

  • It’s possible to display only one profile on the left side by selecting the corresponding pseudo track on the right side. In the toolbar, click on the first button to reset the selection.

  • In case of Visualizer profiles and tracks, the list of tracks can be displayed in gray scale or in RGB mode.

  • In order to better localize the position of the peaks, the toolbar includes a function to display the local maximum on each track in each substance window.
