How to reprocess single quad GCMS data in MSD Chemstation

Hi Community,

 

I'm currently using MSD Chemstation F.01.01.2317 to process my single quad GCMS data (from a 5977B MS). The problem I'm facing is when the method integration events do not integrate my peaks properly I always have to access View --> QEdit Quant Result to manually draw a new baseline for every single peak. I've tried to adjust integration events and could be able to achieve great integrations, however, whenever I select Quantitate --> Calculate the report always shows back the old quantitation results (those with incorrect integrations). Is this something hard coded in MSD Chemstation ? Any ways to make the method apply the new integration events when reprocess a data ?

 

Another issue is also related to data reprocessing. Sometimes the report suddenly showed "%" instead of "ppm" even the method has been set up to use "ppm". When acquiring a new data the unit will go back to normal as "ppm".

 

Any insight or tips would be highly appreciated.

 

Peter.
