    Hi, can you tell more about the mobile phases, and column? I am guessing you are using C18 column running isocratic mobile phases but what are the mobile phases? Is that MPA: Water and MPB: ACN or MeOH? Any Ph modifier? Thank you.

    What is that word you’re saying in reference to the alpha and beta acids? “Prenalated”?

    Prenylated refers to the prenyl- (carbon alkene) tail of the alpha and beta acids. Alpha acids have a single prenyl tail while beta acids have two.

    Hello. Do I need to plot the zero point? In my graph, if the line starts in another point than zero, the results are different and do not make sense to me. Could you help me?
