Do you analyse similar substances using UHPLC? Are you looking for a simple way to improve your resolution?
This application note shows how to separate methyl linolenate and methyl γ-linolenate using two coupled YMC-Triart C18 ExRS UHPLC columns. By using only one column with a typical maximum length of 150 mm the substances could not be fully separated. Using an extended separation length by coupling two columns can easily solve this issue in the absence of longer UHPLC columns.
