LC Systems

Liquid Chromatography (LC) systems are essential analytical instruments used to separate, identify and quantify components within complex mixtures. By utilising differences in interactions between a column stationary phase and a mobile phase, LC systems enable precise analysis across a wide range of applications – from pharmaceuticals and biomolecules to polymers and environmental samples. Modern LC systems combine advanced pumps, injectors and sensitive detectors to deliver accurate, reproducible results with high efficiency.

GPC SYSTEMS

Gel Permeation Chromatography (GPC) is a vital technique for determining the molecular weight and size distribution of polymers. The EcoSEC series from Tosoh Bioscience is a fully automated, compact GPC system designed for reproducible, high-throughput polymer analysis. With dual pump solvent delivery, advanced temperature control, and a high-sensitivity refractive index detector, it delivers outstanding results while reducing analysis time and solvent use. Available as the EcoSEC Elite for ambient operation up to 60°C or the EcoSEC High Temperature model for analyses up to 220°C, the EcoSEC GPC Systems provide reliable, high-performance GPC solutions for a wide range of polymer characterisation applications.
