Hi Richard,
That is a great question and my answer will please you!
What you want to do is create two "sample setups". This procedure is documented in the Advanced Topics manual accessible from the Help menu in PFE (but who reads manuals!).
The opening text is:
Sample SetupsNormally, PROBE FOR EPMA uses the sample setup from the last unknown (or standard if
there are no unknown samples) to create the next new sample setup. Sample setups on the other
hand are designed to allow the user to easily recall a previous sample setup within a current run.
This allows the user to create and re-use multiple setups comprised of different groups of
elements within a single run. In the example below, sample setups for pyroxene and olivine will
be created, each with a different set of elements and conditions, that may be recalled at anytime
during the current probe run.
The saving of a sample setup actually saves only a pointer to the sample selected. All of this
sample's acquisition and calculation options, elements/cations, standard assignments, etc will be
utilized when a new sample is created based on this sample setup.
A new PROBE FOR EPMA run is opened in the usual manner. Ten elements and appropriate
standards for pyroxenes are loaded from the SETUP.MDB database and the STANDARD.MDB
database, respectively. Each element is then calibrated and standardized. Count times,
acquisition and calculation options are adjusted to optimize the analyses and output
requirements.
So basically there are three methods for recalling setups:
File Setups load the selected sample setup and all global flags from a previous probe run
Sample Setups load a sample setup from within the currently open run
Element Setups load a single element setup to the current sample
So you'll first load a file setup from another run, modify as necessary and then click the Save Setups button from the Analyze! window to "save" the selected sample as a Sample setup. This sample setup generally should not contain data so you can continue to modify it further if desired.
Then select the sample setup from the Acquire! New Sample button for manual acquisition or assign a selected sample setup to the position sample list in the Automate! window using the Sample Setups button.
Repeat as necessary for each additional sample setup you want to utilize.
There is also a thread that discusses this here:
