It went from 68:32, 70:30, 72:28. The injections should be within 1% for a pass result. The diluent is ethyl acetate. Injection volume is 1.5ul in a 5ul syringe.
There were other Standards that I ran with the same method and column that passed easily.
Why is it failing only for this one? I'm thinking injection volume is too high.
