Press Release Summary: Thermo Fisher Scientific Inc., the world leader in serving
science, announces the launch of extensions to its flagship range of Hypersil GOLD
HPLC columns. To complement the already extensive range, Hypersil GOLD columns will
now also be available in a phenyl phase, increasing the Hypersil GOLD 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 3 µm and 5 µm particle size) will now also be available with
1.9 µm particle size.



Press Release Body: Thermo Fisher Scientific Inc., the world leader in serving
science, announces the launch of extensions to its flagship range of Hypersil GOLD
HPLC columns. To complement the already extensive range, Hypersil GOLD columns will
now also be available in a phenyl phase, increasing the Hypersil GOLD 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 3 µm and 5 µm particle size) will now also be available with
1.9 µm 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 GOLD is achieved with the phenyl phase. Hypersil
GOLD Phenyl columns are available with 1.9 ?m, 3 ?m and 5 ?m particle sizes.

By offering the Hypersil GOLD C8 and CN phases with 1.9 µm particle size, all
Hypersil GOLD columns are now available with 1.9 µm, 3 µm and 5 µm particle size,
making method transfer to U-HPLC systems, such as the Thermo Scientific Accela High
Speed LC, even 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.
