Sample extraction: diluted diesel sample with acetone. and diluted further with 75:25 acetonitrile:water. Buffer A=75:25 acetonitrile:water and buffer B=acetone. Gradient program from 100% A to 100% B in 30 minutes. But I am not getting sharp peaks.
I am aware that I should not expect hydrocarbons since it is an ESI source. Is there any derivatization methods to detect them?
