PHENOMENEX says it has redefined the industry standard by developing its new core-shell F5 pentafluorophenyl chromotography columns. The robust pentafluorophenyl propyl (PFP) core-shell phase overcomes reproducibility and performance limitations of existing PFP and F5 products, which testing shows produced sporadic…

HPLC columns promise to improve performance
A NEW range of chromatography columns from Thermo Fisher are engineered to ‘significantly increase’ the performance of HPLC separations, without any modification to instruments or methods. The company’s internal laboratory tests show that 4um Accucore XL HPLC columns allow users…
HPLC columns enhance protein and peptide separations
AVAILABLE in analytical, micro, and nano formats, the new Accucore 150-C18 and 150-C4 columns from Thermo Fisher Scientific are designed to improve protein and peptide assay robustness by enhancing peak capacity and run times at moderate operating pressures. Thermo says…
C8 column offers lower hydrophobic retention
THE NEWEST member of Thermo Fisher Scientific’s Accucore range of HPLC columns, the C8, has a shorter alkyl length bonded phase than the equivalent C18 phase. This gives lower hydrophobic retention and, says Thermo, enhances chromatographic performance without generating excessive…
UHPLC columns enable reversed-phase biomolecule separations
THE BENEFITS of reversed-phase biomolecule separations can now be experienced in ultra-high-performance liquid chromatography (UHPLC), says Agilent, thanks to its new Zorbax 300SB-C3 and 300-Diphenyl chromatography columns. This range of columns has particles smaller than 2um and pores of 300 Angstrom,…
Cartridges promise better Flash separations
CLAIMING 40% more surface area than alternative Flash silica cartridges, Biotage says its new Snap Ultra chromatography consumables deliver higher loading capacity and more efficient separations. The use of spherical particles instead if the more usual irregular shaped silica fragments…
HPLC/UHPLC columns to separate proteins and peptides
A RANGE of HPLC/UHPLC columns has been designed specifically for the analysis of proteins and peptides. The Aeris Core-Shell range is said to deliver higher resolution and peak capacities than other bioseparation media, producing sub two micron results on any…
