Applying an external/historical curve to a batch of samples after Acquisition – Ask A Guru
The video below shows how to apply a calibration curve from one batch that contains calibration samples to a batch of samples that contain no calibrators.
This workflow is the same as selecting the external curve in the Acquisition workflow, but may be used on any batch of samples after acquisition.
The features allows the user to run a calibration batch in the morning and use that curve for all subsequent batches for the time period their SOP allows.
HMMMMMM… Maybe your day just got alittle easier.

My Filter String Is Missing After I Updated My Methods Associated Rawfile.. HMMMMMM
So in both the local and master methods, a user can update the associated rawfile to see the peaks they are looking for.
This dialog has an option to update the filter strings. Which makes it easy to do especially if you have hundereds of compounds.
When you do this, the logic looks to the compound database info that is in the Acquisition list and to help it determine the filter with the right precusor and then the extracted ion setting to see which filter contains its value within the range of product ions in the brakets of the mass filter. If everything matches from the newly selected rawfile it sets the filter accordingly. If it doesn’t then the compound will have a little red dot next to its name and a missing filter error lights up.
This typically occurs when the new file has a slightly different filter string and the method’s extracted mass falls outside of the product mass range of the filter.
The following video shows you how to manually fix this issue.
