A Unique C18 Bonded HPLC Column with the Extra Selectivity of a Pentafluorophenyl Phase


ACE C18-PFP is a unique C18 bonded HPLC column from Advanced Chromatography Technologies (UK), which has been developed to provide alternate selectivity to all existing C18 bonded phases. The phase combines the hydrophobic


characteristics of a C18 phase with the alternate selectivity offered by a pentafluorophenyl (PFP) phase – enabling the benefits of multiple interactions to be fully exploited. The phase also exhibits ultra low bleed to ensure LC/MS compatibility and demonstrates excellent temperature and pH stability. At launch, materials are available in 3µm, 5µm and 10µm particle sizes and a full range of column dimensions from high throughput LC-MS through to preparative scale.

Chromatography Problems Solved with Sky™ Inlet Liners


Many chromatographic problems, such as poor response and missing or tailing peaks are caused by activity in the inlet liner. These effects complicate quantification and can be particularly problematic for sensitive analytes. New Sky™ inlet liners from Restek (USA) are extremely inert, assuring complete transfer of analytes to the column, good response, and highly symmetric peaks. The exceptional inertness of these liners is due to a high-tech deactivation process that broadly passivates the liner and packing so that they are inert to a wide variety of reactive analytes.


Some deactivations, such as base deactivation, are effective only for particular target compound chemistries. In contrast, the balanced deactivation of Sky™ liners prevents interactions with many chemical classes. Technical comparisons demonstrating the exceptional inertness of Sky™ liners toward complex pesticide probes, as well as to both acidic and basic compounds are available on Restek’s website. The comprehensive deactivation used for Sky™ inlet liners results in improved sensitivity, accuracy, and reproducibility, which allows analysts to quantify challenging compounds at trace levels with confidence, even when using wool.

New GC Seal is Stable at High Temperatures and Easy to Install


Phenomenex (USA), introduces Easy Seal, an advanced seal for GC columns that addresses common problems with installation and reliability. The new accessory is constructed of a proprietary gold-plated alloy that is softer than widely used stainless steel and can be installed without extraordinary pressure. GC inlets are sometimes bent in the process of installing hard stainless steel seals, but using insufficient force can result in leaks. Easy Seal is also rugged enough to perform at high temperatures and remain stable – a challenge for seals with polymer ring-inlaid surfaces.


"Thorough sealing at the inlet base is an acknowledged problem in the GC industry,” commented Kory Kelly, brand manager for Phenomenex. “Our new Easy Seal resolves the issue by requiring less force to make a leak-free connection without compromising the range of temperatures at which it operates effectively.”


Additionally, Easy Seal is compatible with all Agilent GC instruments. For more information, visit www.phenomenex.com
