This allows you to get a closer look at the baseline of all integrated peaks.

What does Zoom to baseline do?

The behavior of this function depends on where you use it:

• Step 1

  The Zoom to baseline function allows you to get a closer look at the base of all the peaks of the chosen signal. If you defined an integration range, only this range is considered.

  Click to check the peaks near a possible baseline.

  The baseline zoom factor is automatically stored in step 1 in order to be applied in the next steps.

• Step 2 and 3

  In step 2 or 3, click to show baselines using the previously stored zoom factor. Use this function to compare baselines in different injections.

  The Zoom to baseline function always applies a constant Y-axis delta. If a baseline is shifted, this delta will also be shifted according to your baseline. The X-axis is not affected. If you choose a specific retention time range, this time range will remain unchanged

If the signal is drifting out of sight in the plot window: Zoom into the relevant time range, irrespective of the response values where you want to see the signal, then click . The signal is then shifted into view again, while maintaining the same response range.
