Hi everyone! I'm a new user of a XEVO TQD. I'm having some problems trying to tune bisphenol A with both manual and intellistart tuning. I've tried with ESI- and I'm infusing 1,2 ppm of BPA. Also trying to perform a manual tuning I was not able to see a nice peak comparing it to noise. Image
Not sure what extra info I could give you but just let me know.
Thanks a lot!
