Hi All,
I have uploaded a new version of ACSM_Local ( to the ACSM uses' site which fixes the bug in the PMF export routines described below by Jay.
The new version also contains an edit to the calibration procedure allowing the user to select whether to use the sample, filter or difference MS data to do the calibration (top right hand corner where the old, unnecessary and confusing NO3/SO4 dropdown was). A word of caution if you do use the difference MS data, you'll want to add a pause to the first m/z  in your scan table (usually m/z 15) so that you're not measuring while the valve is switching or the air in the tube between the valve and the inlet has time to flush. I've been using a value of 600 for testing this which may be excessive, but works fine.

Hi all,


Please find attached a new version of EETQA tool that fixes a few bugs in the application of correction factors within the time series calculations.  The field for entering a time-dependent CE correction on the main panel has also been moved to a more visible location.


Please note that one bug affecting EETQA was found to actually exist within ACSM _local.  Specifically, during export of PMF matrices, the relative ion transmission correction is hardcoded to always use the default values rather than the user-determined correction.  We no longer use the bugged procedure in EETQA, and I will momentarily let Aerodyne know of the issue.
