I'm using for a while now a Waters Acquity UPLC with Xevo TQD mass spectrometry to analize Mycotoxins.
The equipment was out of use for 2 month becouse of problems with the turbo pump on the mass spectrometer.
Now that the mass spec is fixed i was running some test and i noticed that the sensitivity was very low compared to analisys done in march.
The standards are new and even when injected pure in to the LC system they showed a very small peak.
The specialist from waters who fixed the mass spec did some infusions into the mass spec with standards to evaluate the sensitivity and to him it seemed normal.
Anyone with some ideia to what is happening?
