A straightforward separation of 10 closely related forms of vitamin E with a Kinetex 2.6 µm F5 HPLC column and under reversed-phase conditions. The 10 closely related structures were chromatographically separated by the multiple selectivity interaction mechanisms of the Kinetex F5 phase and Water/Methanol mobile phase.

This method presents the reversed-phase retention and detection of 7 polar Neonicotinoids and 4 deuterated-internal standards by LC-MS/MS and with a Kinetex 2.6 Biphenyl HPLC column. The Kinetex Biphenyl phase demonstrated significant polar compound retention and selectivity.

Described in this application note are the details for an investigation of basic compound peak shape across four different alkyl C18 stationary phases that are all based upon the same core-shell HPLC/UHPLC particle morphology.

In this application, is the investigation into the relative selectivity of four different C18 stationary phases when applied to the reversed phase retention of six extremely polar artificial sweeteners.

For this analysis, we developed a fast, robust, and efficient separation on a Kinetex 2.6µm Polar C18 phase. This is a highly robust, core-shell stationary phase capable of providing increased efficiency over fully porous products. The Kinetex Polar C18 functionality provides unique polar selectivity that was critical in effectively retaining and separating these phenolic antioxidants.
