HPLC Method of Ferrozine on Newcrom BH Column
High Performance Liquid Chromatography (HPLC) Method for Analysis of Ferrozine
Ferrozine is a common reagent and indicator used for analyzing and detecting iron. Multi-charged molecules, such as Ferrozine, generally have a tendency to exhibit poor peak shape on reverse-phase HPLC columns, where they show significant tailing.
This compound can be retained with great peak shape on a Newcrom BH mixed-mode column. Ferrozine can be measured at low UV. Using a Newcrom BH mixed-mode column and a mobile phase consisting of methanol (MeOH) and water with perchloric acid (HCLO4) buffer, Ferrozine can be retained and UV detected at 280 nm with precise resolution.
