Separation type: Liquid Chromatography Mixed-mode
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.

Application Column
Newcrom BH
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
