May I know is it cause of the incorrect cartridge used?
Or can anyone give suggestions of the cartridges which I could use?
Thank you...

I am facing a problem with analyzing acetaminophen in water. I used Agilent Bond Elut Plexa for SPE extraction following EPA1694. However, the recovery for the spike is almost 0% while surrogate recovery (labelled acetaminophen) is only 25%.
