Hypercarb HPLC and UHPLC Columns

Porous graphitic carbon (PGC, Hypercarb ) has unique properties as a stationary phase in high-performance liquid chromatography (HPLC). Its chemical surface properties distinguish it from more conventional LC packings such as bonded-silica gels and polymers.

Functionalization/Passivation of Porous Graphitic Carbon with Di

! 2! 1. INTRODUCTION Porous graphitic carbon (PGC) is an important alternative to silica-based supports for liquid chromatography (LC).[1] PGC has two considerable advantages over silica. The first is stability, both at extremes of pH (from 10 M HCl to 10 M NaOH

Robust Separation of Polar Compounds Utilising Porous

Porous graphitic carbon columns can be used successfully for the retention and separation of extremely polar compounds, which are problematic to retain in reversed-phase conditions. These columns offer a unique polar retention mechanism that often can be implemented simply, and can produce robust separations of extremely polar species under typical reversed phase conditions.

In addition to using porous graphitic carbon in sample clean-up, analysis of PSTs and TTX using a HPLC-FLD post-column method with a porous graphitized column has been described previously (Rey, Botana, lvarez, Antelo, Botana, 2016). This column has

Analysis of triacylglycerols on porous graphitic carbon

2007/7/20The retention behaviour of several triacylglycerols (TAGs) and fats on Hypercarb, a porous graphitic carbon column (PGC), was investigated in liquid chromatography (LC) under isocratic elution mode with an evaporative light scattering detector (ELSD).Mixtures of

Porous graphitic carbon shows promise for the rapid

1995/5/5A rapid and simple HPLC method has been developed and used to separate the polar metabolic conjugates of AZT, chloramphenicol, and β-estradiol based upon the use of porous graphitic carbon. The HPLC system is sufficiently selective to resolve the polar drug conjugates from their parent compounds and from endogenous material present in urine.
