Hi
I work as a chemist in a pesticide quality control laboratory. I have sever problem in switching from reverse phase to normal phase mobile phase. I most often use reverse phase mobile phase. But for deltamethrin analysis I have to use normal phase mobile (pentane: 1-4 dioxan in the ratio of 96:4) which create problem. Can any body help me out by providing reverse phase method for determination of deltamethrin. I have Agilent 1260 infinity series HPLC
Best Regards
