Thermo Fisher expand their range of HPLC Columns

Thermo Fisher Scientific Inc. has announced an extension to its range of Hypersil GOLDT HPLC columns. Hypersil GOLDT columns will now also be available in a phenyl phase, increasing the Hypersil GOLDT range of selectivities for RP (reversed phase) chromatography.

In addition to the introduction of the phenyl phase, the existing Hypersil GOLDT C8 and CN phases (until now only available with 3 µm and 5 µm particle size) will also be available with 1.9 µm particle size.

The Hypersil GOLDT Phenyl stationary phase contains a butyl linker for better alignment with aromatic molecules which, according to Thermo Fisher Scientific, allows 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 GOLDT Phenyl columns are based upon the same high purity silica, the peak shape and sensitivity delivered by Hypersil GOLDT is achieved with the phenyl phase.

The expanded range of Hypersil GOLDT columns offers chromatographers even more flexibility in choosing the correct column whether they are using conventional or ultra-high pressure LC systems.
