I`m currently working in some pesticides residue analysis with Waters Acquity Class H UPLC with Xevo TQD Mass Spectrometry.
I set up the system today and run some samples to plot the curve, but when i looked at the chromatogram i realised there was a huge noise until 6,50 minutes when it dissapeared. Anyone knows what its heppening here?
