General description

HPLC column
LiChrospher® RP-select B is a versatile traditionally produced spherical silica gel carriers with reversed phase properties and with the hydrophobicity of a C-8 phase. This carrier is very well suited for the separation of basic compounds, but with still good properties for the determination of neutral and acidic compounds. This sorbent is packed into a Hibar 100-4.6 HPLC column. For mounting of a LiChroCART 4-4 guard column, the guard column holder 1.51487 has to be used.

Application


  • Simultaneous quantification of delta-9-THC, THC-acid A, CBN and CBD in seized drugs using HPLC-DAD: This study utilizes high-performance liquid chromatography with diode-array detection (HPLC-DAD), employing a LiChrospher® RP-select B column to effectively separate and quantify cannabinoids in forensic samples, highlighting its application in legal and forensic settings (Ambach et al., 2014).

  • Structural characterization of stress degradation products of Darunavir: Employing LC-MS/MS alongside HPLC, this research underscores the utility of the LiChrospher® RP-select B column in the stability analysis of HIV medications, crucial for ensuring drug safety and efficacy (Rao et al., 2014).

  • RP-HPLC separation and characterization of unknown impurities of Darunavir: This study demonstrates the column′s role in identifying and quantifying impurities in HIV-protease inhibitors, contributing to the pharmaceutical industry′s quality control measures (Nageswara Rao et al., 2013).

  • Quantification of pralidoxime in urine by ion pair chromatography: The LiChrospher® RP-select B column is applied in a biomedical context to monitor therapeutic agents in clinical settings, supporting patient treatment regimes (John et al., 2012).

  • Liquid chromatography/electrospray tandem mass spectrometry method for determination of cefuroxime: This analytical method facilitates the study of pharmacokinetics in clinical pharmacology, using the LiChrospher® RP-select B column for precise drug monitoring in plasma (Partani et al., 2010).
