Separation of positional isomers using reverse phase and HILIC analysis! An additional step to add to C18 and HILIC columns.
The "F5 (PFP) HPLC/UHPLC column" for metabolomics is a reversed-phase column with selectivity different from C18. By incorporating it as a second or third choice column in reversed-phase systems, the range of substances for LC analysis is broadened. Four retention mechanisms—hydrogen bonding, dipole-dipole interactions, π-π interactions, and hydrophobic interactions—complexly influence each other to exhibit unique retention characteristics and stereoselectivity. 【Features】 ■ Retains highly polar basic compounds without ion-pair reagents ■ 100% water mobile phase is usable ■ Suitable for LC/MS due to retention at high organic solvent concentrations ■ Supports both analysis and fractionation *For more details, please refer to the PDF document or feel free to contact us.
