Different conditions for one element, channel, crystal

[Rom]

Good day,
Could you advice how we can measure one element in different conditions. Sometimes the first part of samples needs set A of BG positions and other settings for the element Nn (for the channel, crystal), but second part of samples needs set B of BG positions and other settings for element Nn (for the channel, crystal) .

In this case we can't repeat the element in the element list of (for the channel, crystal) in Acquire!. So, we need to start 2 different runs (sessions). How we can start them (if it possible) successively and automatically, without operator?

Easy. Just use the Multiple Sample Setups feature in the Automate! window as seen here:



With this feature you can automatically re-run the same digitized positions using a number of sample configurations. Usually this is done for thin film analysis where one needs to run the same elements at different beam voltages, or for the constant k-ratio method where one runs the same elements at different beam currents.  But it could be any differences in the sample setup, including different background positions.

Once you've created a bunch of sample setups with your different background positions, and added them from the Analyze! window using the Add To Sample Setups button, you click the Multiple Setups button in Automate and select them as described in this post:

Note that the Use Y Increment feature can make sure that each analysis is automatically incrementing the stage Y axis to avoid damaging the sample.

Note that you can also define multiple background positions for a single sample setup by using the multi-point background (MPB) method:

Wow, excellent!
1. Peak positions will be the same through the whole session and we need to do the peaking just 1 time for each element (for each element line to precise).
Isn't it?

2. We can use Y increment through Automate!, Multiple Setups - it is clear, thank you. How we can change the increment distance?

When you create a new sample just edit the background positions. Everything else should stay the same.

It's the value displayed in the Automate! window "Re-Standard Y Increment" text control.

Thank you!
