Hello both,

is there any method published anywhere which can be realistically thought to have no matrix effect?
Not just absence of mentioned effect, but truly verified absence of one and how would one go about proving it?

If you had a gun pointed to your head and someone asks you to develop an LC-MS/MS method without matrix effect for, say, Duloxetine or Simvastatin where would you start?

Pass or fail!
