Hi everybody,
When you are running the P/A tuning solution on the 7900 ICP-MS do you select all the masses in the P/A tune solution or do you just use the masses form the method that you are using.
Thanks.

Hi Edgar,
Thank you for your response. That's very helpful.
Am I correct in thinking that the in-batch P/A adjustment is only performed on samples marked as calibration standard (CalStd)? If so, if samples are run prior to that standard then is the P/A adjustment performed retroactively or do those early samples use the P/A factor that was initially stored onto the icpms hardware?
Thanks again!
Matt.
Hi Matt,
the in-batch p/a factor is calculated with the use of all the CalStd's.
the p/a factor in batch is used for all the measurements in the batch. if an external p/a is performed then the last external p/a factor is used (and stored in the batch) if no internal p/a factor is checked in the batch.
