o Stable from pH 1 to 14 at high temperatures in a wide range of solvents

Product detail:

Hypercarb is a unique material for HPLC manufactured by Thermo Hypersil-Keystone. Hypercarb consists of fully porous spherical carbon particles comprised of flat sheets of hexagonally arranged carbon atoms. The carbon atoms have a fully satisfied valence and offer completely different retention and selectivity to silica and polymer based phases.

Hypercarb can be used for RP and NP chromatography with a pH range from 1 to 14, and at extremes of temperature. Hypercarb excels in the analysis of structurally related components (e.g. stereo- and diastereoisomers and positional isomers) where no separation occurs on conventional materials.

Hypercarb retains polar compounds via a 'polar retention effect' where a stronger analyte-sorbent attraction occurs as the polarity of the analyte increases, so the more polar the analyte the longer it's retention time compared to silica-based phases. Due to the unique retention mechanism of Hypercarb, we recommend that you do not use a column longer than 100mm or 150mm in length. Please contact us for technical assistance.

Other column dimensions and hardware designs are available. Please contact us for more information if you do not see the exact column that you are interested in.
