Is there a way to manually tangent skim peaks in MassHunter Qualitative Analysis? They have this tool in OpenLab Chemstation (shown below) but I cannot find a way to do it manually in MassHunter.
As far as I know Qual does not offer these types of integration tools. Quant has a few available tools, but not a tangent skim tool specifically.
The best you will be able to do in Qual is to use the ChemStation integrator and try adjusting the options and initial settings as best as possible and then use the Baseline At Valleys timed event to force a tangent skim.
Depending on your data you will probably first want to switch the Baseline correction mode from Classic to either Advanced or No Penetration.
Then you can add Baseline At Valleys On and Off events around the peaks that you want to adjust. Note the difference in integration of the 13.268 peak with Baseline At Valleys On.
There are a few different parameters you can adjust in the ChemStation Integrator options tab that will determine how shoulders are detected and how and when tangent skimming is performed. In addition to the help file entries for these settings, which can quickly be accessed by placing your cursor in one of the parameter entry fields and pressing the <F1> key, there are some additional tips and documentation available in these documents.

I played around with the integration parameters based on the documents you referred me to but I am still having a hard time getting those smaller peaks integrated properly. Is is possible for me to send you the file I am working on (via DropBox or some other file transfer software) and you can take a look at it?
Please let me know.
