I'm trying to develop new methode for determination of Folic acid and Cyanocobalamin by simultaneous mesurement. Im Using the Paired ion Chromatography (tetrabutylammonium phasphate and Heptane sulfonic Acid) for mobile phase, and C18 Column. But the peak didnt separate well. and the retention time of that two compound are still the same, which is 1.4 min.
What can I do now? And what paired ion Chromathography that I should use? Can somebody tell me?
