Popis

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 P_o/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

(Rabti et al., 2024).


• Heart-cut bidimensional achiral-chiral liquid chromatography applied to the evaluation of stereoselective metabolism, in vivo biological activity, and brain response to chiral drug candidates targeting the central nervous system.: The study uses the Discovery^® HS F5 HPLC Column in a bidimensional achiral-chiral liquid chromatography setup to evaluate the stereoselective metabolism and biological activity of chiral CNS drug candidates. (Battisti et al., 2016).


• Chromatographic separation of arsenic species with pentafluorophenyl column and application to rice.: This paper describes the separation of arsenic species in rice using a pentafluorophenyl column, highlighting the effectiveness of the Discovery^® HS F5 HPLC Column for environmental and food safety applications. (Baba et al., 2014).


• Advantages of pentafluorophenylpropyl stationary phase over conventional C18 stationary phase--application to analysis of triamcinolone acetonide.: The research compares the Discovery^® HS F5 HPLC Column to conventional C18 columns, demonstrating superior performance in the analysis of triamcinolone acetonide. (Havlíková et al., 2008).
