General description
Guidelines for transferring a C18 method to Discovery® HS F5:
Generally, bases are retained longer on the HS F5 than on a C18. Increasing the organic content of a C18 separation 5 to 10 percent will generally provide similar retention on an HS F5. Results with other compounds are highly variable. However, it is generally true that solutes with log Po/w values less than 2.5 will be retained longer on HS F5 compared to a C18. The degree of difference is highly solute dependent.

The Discovery® HS F5 bonded phase provides reversed-phase separations that are distinctly different from C18 columns. However, compounds will generally elute within the same retention time window, making most C18 methods easily transferable.
Application
- Determination of 6-hydroxy-1-methyl-1,2,3,4-tetrahydro-beta-carboline, 5-hydroxytryptamine and 5-hydroxyindole acetic acid in the neonatal rat brains using high performance liquid chromatography-electrochemical detection.: This study highlights the use of the Discovery® HS F5 HPLC Column for the sensitive detection of neuroactive compounds in neonatal rat brain samples, advancing our understanding of neurological development and neurotransmitter dynamics (Mao et al., 2009).
- Advantages of pentafluorophenylpropyl stationary phase over conventional C18 stationary phase--application to analysis of triamcinolone acetonide.: This research showcases the superior performance of the Discovery® HS F5 HPLC Column in analyzing corticosteroid formulations, providing insights that could lead to improved analytical methodologies in pharmaceutical analysis (Havlikova et al., 2008).
- Determination of ephedrine alkaloids in Ephedra natural products using HPLC on a pentafluorophenylpropyl stationary phase.: Utilizes the Discovery® HS F5 HPLC Column for the precise and efficient separation of ephedrine alkaloids, contributing to safer and more effective use of Ephedra in herbal supplements (Pellati and Benvenuti, 2008).
- Fast high-performance liquid chromatography analysis of phenethylamine alkaloids in Citrus natural products on a pentafluorophenylpropyl stationary phase.: Demonstrates the efficiency of the Discovery® HS F5 HPLC Column in the rapid analysis of phenethylamine alkaloids, enhancing the quality control of Citrus-based dietary supplements (Pellati and Benvenuti, 2007).
- High-performance liquid chromatographic method with UV photodiode-array, fluorescence and mass spectrometric detection for simultaneous determination of galantamine and its phase I metabolites in biological samples.: This study uses the Discovery® HS F5 HPLC Column to simultaneously quantify galantamine and its metabolites, aiding in the pharmacokinetic profiling of this Alzheimer′s disease medication (Malakova et al., 2007).
Features and Benefits
- Unique selectivity
- Similar retention to C18 (sometimes requires stronger mobile phase)
- Excellent peak shape
- Stable, low-bleed LC-MS separations
- Scalable separations from 3 to 10μm particle sizes
