Additions to Hypersil Gold HPLC column
range
To complement the range, Hypersil Gold columns will now also be available in a phenyl phase, increasing the range of selectivities for RP (reversed phase) chromatography
In addition to the introduction of the phenyl phase, the existing Hypersil Gold C8 and CN phases (until now only available with 3um and 5um particle size) will now also be available with 1.9um particle size The new Hypersil Gold Phenyl stationary phase contains a butyl linker for superior alignment with aromatic molecules, allowing for enhanced pi-pi interactions thus increasing the retention of these aromatic molecules

The butyl linker also imparts moderate hydrophobicity making the columns ideal for the separation of analyte mixtures with varying polarity and aromaticity.
Because Hypersil Gold Phenyl columns are based upon the same high purity silica, the outstanding peak shape and sensitivity delivered by Hypersil is achieved with the phenyl phase.
Hypersil Gold Phenyl columns are available with 1.9um, 3um and 5um particle sizes.
By offering the Hypersil Gold C8 and CN phases with 1.9um particle size, all Hypersil Gold columns are now available with 1.9um, 3um and 5um particle size, making method transfer to U-HPLC systems, such as the Thermo Scientific Accela high speed LC more convenient.
The expanded range of Hypersil Gold columns offers chromatographers even more flexibility in choosing the correct column whether they are using conventional or ultra-high pressure LC systems.
