Tosoh Bioscience celebrates 40 years of SEC/GPC expertise
Tosoh Profile
The development of the first TSKgel GPC column in 1971 had set the course for a long and proud history of size exclusion chromatography at Tosoh.
At that time the lack of suitable tools for the analysis of Tosoh’s polymer products was the driving force behind the development of TSKgel chromatography columns. Today the range of SEC related products comprises of SEC/GPC systems – e.g. the compact, semi-micro EcoSEC system representing the 8th generation of SEC instrumentation technology - and stationary phases for both modes of size exclusion chromatography, aqueous gel filtration (GFC) and organic gel permeation chromatography (GPC):
- TSKgel SW series silica columns, the biotech industry’s standard for protein analysis
- Polymeric TSKgel PW columns for analysis of water soluble polymers
- TSKgel Alpha & SuperAW columns suitable for aqueous and organic SEC
- Polystyrene based TSKgel HXL, HHR and SuperH columns for GPC
Latest additions to the SEC column lines are linear, semi-micro SEC columns, the TSKgel SuperMultiporePW series, designed for fast size distribution analysis of water soluble polymers. Two brochures, the TSKgel GPC column brochure and the latest edition of the TSKgel SEC column brochure provide an excellent overview over the complete range of TSKgel size exclusion columns.

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.
