I have been given a sample of QAC (a mix of DDAC, ADBAC and ADEBAC) which was many orders of magnitude stronger than I was told. The upshot is that I have massively contaminated both the chromatogrphay side (Waters UPC2) and the fluidics on the MS (Xevo G2XS QTOF). I have been flushing for days with all manner of different solvents but the signals are still huge. Any suggestions?
cheers.
