Agilent offers single source for HPLC supplies and services

IN A bid to win lucrative new business supplying consumables and servicing for other manufacturers’ HPLC instruments, Agilent has launched its new CrossLab HPLC offering. The move expands the CrossLab operation into high-performance liquid chromatography (HPLC) in addition to the…

Drying of aqueous HPLC fractions made faster and easier

A HIGH throughput method for drying high performance liquid chromatography (HPLC) fractions containing water is described in a new white paper from Genevac. Many lab workers experience difficulty in drying HPLC purification fractions. While the more volatile acetonitrile and methanol…

UHPLC delivers ‘exceptional’ productivity

CLAIMING the lowest gradient delay volume and unmatched flow precision, the Thermo Scientific UltiMate 3000 XRS ultra-high performance liquid chromatograph (UHPLC) is the newest member of Thermo’s UHPLC+ range. The company says the instrument offers new sampling and detection capabilities,…

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…

Thermo Fisher’s latest invention: water

ULTRA High Pressure Liquid Chromatography (UHPLC) is a powerful separation technique involving high pressure (around 350bar, 5000psi or more) and small stationary phase particles of typically 2um or smaller. It also requires a solvent, of course. Thermo Fisher has introduced…

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…

HPLC with added supercriticality

A NEW hybrid ultra high-performance liquid chromatography (UHPLC) launched by Agilent Technologies is the first to incorporate supercritical fluid chromatography capabilities. The 1260 Infinity Hybrid SFC/UHPLC system allows the researcher to select the most suitable separation method for the sample…

Online calculator generates HPLC methods

A NEW online tool to generate HPLC and UHPLC methods has been unveilied by Phenomenex. Kinetex Calculator produces a method based on the running conditions that are entered online, which should provide an optimised result for users. It also calculates…

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…

Nano-UHPLC boosts proteomics research productivity

ANY INSTRUMENT that delivers a 34% improvement in laboratory productivity is one that lab managers have to take seriously. Thermo says that researchers at the Centre for Experimental Bioinformatics (CEBI) at the University of Southern Denmark have seen a 34%…
