GPC elution profile of intraday reproducibility of the EcoSEC High Temperature GPC System

EcoSEC ambient is a compact system for the gel permeation chromatography (GPC) up to 60 ° C, which can perform analysis with conventional as well as semi-micro columns. Short analysis times and reproducible results are achieved especially in combination with the linear TSKgel SuperMultipore GPC columns. Above all, the system is characterized by an exceptional reproducibility of the thermostatically controlled pump flow and a highly stable baseline of the dual flow RI detector. It is compatible with all GPC/Size exclusion chromatography (SEC) solvents.

The new EcoSEC High Temperature GPC System incorporates the proven design and technology used in our ambient EcoSEC GPC instrument. The EcoSEC-HT system for high temperature analysis of engineering plastics provides total system temperature control up to 220 ° C, auto-sampler up to 24 samples, dual pumps, spacious column oven and temperature controlled dual flow RI detector with proven baseline stability. The system can be extended with an optional sample preparation system with a temperature control range 40-220 °C in an aluminum heating block for 24 samples. Safety features of the high temperature system are controlled by temperature and gas sensors in the pump oven and the column oven. All in one design of the EcoSEC-HT system can be controlled by the workstation software.

In order to prevent possible solvent freezing, solvent holder maintains a constant temperature at 40 °C. Temperature controlled pump heads and solvent lines improve baseline stability by removing the effect of temperature fluctuations. This results in consistent and accurate flow rates and reproducible molar mass determinations. Column oven can accommodate 8 columns of 30 cm length.

SEC is a popular method for the separation of natural or synthetic polymers and is commonly used for the determination of molecular weight and molecular weight distributions. More than 40 years scientists developed at the first Tosoh TSKgel GPC column to characterize polymers which have been produced within the Group. It has today a comprehensive range of products designed to be used in the chemical, petrochemical and automotive industries.

The Tosoh Bioscience Separations business unit is based in Im Leuschnerpark 4, 64347 Griesheim, Germany and provides extensive technical application support to training and workshops. Tosoh Bioscience is a subsidiary of Tosoh Corporation, a Japanese chemical company generated sales of about $ seven billion in a global network with more than 11,500 employees.
