I am developing a method for plasticizers with LCMS and I keep getting large peaks in my blank, even in “No injection mode”. I suspect the plasticizers are in my mobile phase, because the longer I equilibrate the system, the larger the peaks.
I keep getting the peaks with bottled water, so I m having trouble tracing how they got into my mobile phase! Has anyone found plasticizers in bottled LCMS water? Can anyone help with this kind of contamination?
