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
- Optimization and validation of a bioanalytical HPLC-UV technique for simultaneous determination of underivatized phenylalanine and tyrosine in the blood for phenylketonuria diagnosis and monitoring.: This study utilizes the Discovery® HS F5 HPLC Column to develop an HPLC-UV method for the simultaneous determination of phenylalanine and tyrosine in blood, significantly advancing the diagnostic and monitoring capabilities for phenylketonuria (Rabti et al., 2024).
- A new RP-HPLC method as an auxiliary tool for optimization of sample preparation procedures for tracing of PPCPs of different hydrophilicities.: Demonstrates the application of the Discovery® HS F5 HPLC Column in optimizing sample preparation techniques for the detection of pharmaceuticals and personal care products in environmental samples, enhancing the analysis of diverse hydrophilic compounds (Portillo-Castillo et al., 2021).
- "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.: Utilizes the Discovery® HS F5 HPLC Column in a novel bidimensional chromatographic setup to study the stereoselective metabolism of CNS-targeting chiral drugs, contributing to a deeper understanding of their pharmacological profiles (Battisti et al., 2016).
- HPLC method development, validation, and impurity characterization of a potent antitumor indenoisoquinoline, LMP776 (NSC 725776).: This research employs the Discovery® HS F5 HPLC Column for developing an HPLC method to identify and characterize impurities in the antitumor drug LMP776, ensuring drug purity and compliance with regulatory standards (Wang et al., 2016).
- Development studies on determination of preservatives decomposition products.: Showcases the application of the Discovery® HS F5 HPLC Column in the analysis of decomposition products of preservatives, enhancing the safety assessments of food and pharmaceutical products (Zabrzewska et al., 2014).
