New and Improved Glass Chromatography Columns The new Omnifit®

EZ glass chromatography columns from Diba Industries, Inc provide enhanced performance for low- to mid-pressure liquid chromatography or flow chemistry applications. With improvements based on surveys with thousands of lab technicians, the columns are redesigned from conventional Omnifit columns for easier use and more versatility.

EZ columns’ redesigned end pieces allow easier assembly, and improved ergonomics simplify height adjustment of the threaded adjustable plungers. PEEK™ column tube threads won’t chip or break, and upgraded anti-roll features prevent accidental breakage. Omnifit EZ columns are available in new sizes, including 5mm ID in a range of lengths, and 33cm lengths for all ID sizes. The fittings kit was enhanced to include Diba’s patented Click-N-Seal®

fitting for 10-32 conical port connections to ensure the correct torque is always applied.

EZ columns maintain many of the same popular features of conventional Omnifit chromatography columns. Precision borosilicate glass provides inertness, visibility and performance. Fixed or adjustable PTFE end pieces include dual o-rings for a secure seal. Superior frit placement ensures bed support and even distribution of sample flow.

EZ columns are manufactured by Diba Industries, Inc and distributed globally through Kinesis Inc. For more information visit:

New Size Exclusion Columns for UHPLC

TSKgel UP-SW3000, a new two micron stationary phase, is the latest addition to the renowned TSKgel SW series of silica based gel filtration columns from Tosoh Bioscience. Packed into UHPLC column hardware it supports a smooth transfer of existing HPLC methods to UHPLC technology. TSKgel UP-SW3000 features the same surface modification and pore size as the well-established TSKgel G3000SWXL being the gold

standard for QC of therapeutic antibodies in Biopharma for decades. Over 40 years of experience in developing and producing SEC stationary phases are incorporated into the new series of UHPLC columns for the analysis of proteins in the range of 10 to 500 kDa.

Methods developed on conventional gel filtration columns can easily be transferred to UHPLC technology when using TSKgel UP-SW3000. The 30cm column delivers increased resolution between mAb fragments, monomers, and aggregates. A 15cm column is available to shorten analysis time while maintaining resolution. To achieve maximum resolution and fully exploit the potential of the columns the use of a UHPLC system is highly recommended. A so-called DC (direct connect) guard column can be attached directly to the analytical column to minimise extra column band broadening.

TSKgel SW columns stand out from other silica-based high performance size exclusion columns by virtue of their large pore volumes. They are based on highly porous, ultra-pure silica particles, the surface of which has been shielded from interacting with proteins by applying a proprietary surface chemistry. This ensures highest recoveries and accurate quantitation. The validated manufacturing and packing process delivers a reliable batch-to-batch reproducibility.

High-Performing SPME Fibres Now Available from Restek

Solid phase microextraction (SPME) automated sample preparation reduces sample handling and solvent consumption, and it has many applications in environmental, food, clinical, and other industries. New Restek®

PAL SPME fibres are high-performing fibres that meet or exceed the

performance of other brands. Our reliable SPME fibres feature an aluminium hub that is more durable than plastic. These fibres are optimised for PAL system autosamplers and are compatible with most GC inlets. Restek SPME fibres are suitable for a wide range of analyte chemistries and sample matrices. Restek’s SPME product line is continually expanding and currently includes SPME fibres for both polar and nonpolar target analytes across a wide range of molecular weights and volatilities.
