Extension of TSK-GEL ODS-100 reversed phase column line
Tosoh Bioscience is extending the portfolio of TSK-GEL ODS-100 reversed phase columns by a new 3µm TSKgel ODS-100Z stationary phase and additional column dimensions for all TSK-GEL ODS-100 phases.
Tosoh Bioscience is extending the portfolio of TSK-GEL ODS-100 reversed phase columns by a new 3µm TSKgel ODS-100Z stationary phase and additional column dimensions for all TSK-GEL ODS-100 phases. TSKgel ODS-100V and TSKgel ODS-100Z columns incorporate best-in-class surface properties to limit secondary interactions of basic, acidic and chelating compounds. They offer high efficiency and symmetrical peak shapes.
TSK-GEL ODS-100Z columns offer strong retention and high selectivity when separating homologues series of non-polar and polar compounds. They contain a high density monomeric C18 bonded phase for maximum retention of small molecular weight compounds. When using low pH mobile phase conditions, TSK-GEL ODS-100Z columns outlast other RP columns by providing stable retention. This popular C18 phase is now available in 3µm particle size. For both, 3µm and 5µm particle size the choice of available column dimensions was expanded.
TSK-GEL ODS-100V columns provide strong retention and high selectivity for polar solutes. The TSKgel ODS-100V stationary phase is less hydrophobic than ODS-100Z phase. Monomeric bonded phase chemistry and highly efficient endcapping provides complete wetting and retention stability in 100% aqueous mobile phases. Due to continued requests 3 mm ID and other lengths were added to the existing 2 and 4.6 mm ID TSKgel ODS-100V, 3µm and 5µm column line.
A new brochure on reversed phase chromatography provides detailed information on the broad range of TSK-GEL reversed phase columns. Visit www.tosohbioscience.com to download the brochure or to order your personal copy.
Determining Enhanced Sensitivity to Odors due to Anxiety-Associated Chemosignals with GC
May 8th 2025Based on their hypothesis that smelling anxiety chemosignals can, like visual anxiety induction, lead to an increase in odor sensitivity, a joint study between the University of Erlangen-Nuremberg (Erlangen, Germany) and the Fraunhofer Institute for Process Engineering and Packaging (Freising, Germany) combined behavioral experiments, odor profile analysis by a trained panel, and instrumental analysis of odorants (gas chromatography-olfactometry) and volatiles (gas chromatography-mass spectrometry).
Investigating 3D-Printable Stationary Phases in Liquid Chromatography
May 7th 20253D printing technology has potential in chromatography, but a major challenge is developing materials with both high porosity and robust mechanical properties. Recently, scientists compared the separation performances of eight different 3D printable stationary phases.
Detecting Hyper-Fast Chromatographic Peaks Using Ion Mobility Spectrometry
May 6th 2025Ion mobility spectrometers can detect trace compounds quickly, though they can face various issues with detecting certain peaks. University of Hannover scientists created a new system for resolving hyper-fast gas chromatography (GC) peaks.
