Hi and Hello,
I have some problems with the analyses of amidotrizoeacid and Sulfamethoxazol in Riverwater.
I conzentrate the substanzes with an C18 SPE and analyse it with a Q-TOF massspektrometer.
I can See Carbamazepin, but can not see Amidotrizoeacid and sulfametoxazol after SPE,
Is someone here who can help me with this Problems?

Thanks,
Sascha from Germany
