Analysis by LC-MS/MS of polar pesticides in fruits and vegetables using new hybrid stationary phase
Highly polar pesticides are frequently used in agriculture. However, their physicochemical properties make very difficult the analysis of these compounds following common procedures.

Normal-phase high performance liquid chromatography of estradiol derivatives on amino- and diol-columns [PDF]
The retention behavior of estradiol derivatives was studied by HPLC on chemically bonded polar stationary phases: commercially available amino and diol- columns, as a function of the heptane-propan-1-ol as the mobile phase, when the volume fraction of ...

Electrochromatographic retention of peptides on strong cation‐exchange stationary phases [PDF]
AbstractWe analyze the systematic and substantial electrical field‐dependence of electrochromatographic retention for four counterionic peptides ([Met5]enkephalin, oxytocin, [Arg8]vasopressin, and luteinizing hormone releasing hormone (LHRH) ) on a strong cation‐exchange (SCX) stationary phase.
