Profile: Tosoh Bioscience LLC offers a comprehensive line of media and prepacked columns for all common modes of liquid chromatography. Our ion exchange chromatography (IEC) is used for the concentration of products from dilute feedstreams in a capture step and in high resolution analytical analysis or polishing steps.Our process development columns are easy-to-use, pre-packed columns containing our Toyopearl resins. They provide a convenient, low-cost alternative for the evaluation of Toyopearl ligand chemistries to our traditional LabPaks. Our wavelength UV detector is available as an optional component for the EcoSEC GPC system. The detector wavelength is variable from 195 to 350nm and the detector flow path and electronics are optimized for the use of semi-micro columns. The volume of the flow cell is reduced to 2µL, while the shortest time constant is 0.5 seconds.
