EcoSEC Elite GPC System

EcoSEC™ Elite GPC System

The EcoSEC Elite GPC System is a dedicated GPC instrument developed for fast polymer analysis.

The all-in-one design concept delivers these benefits:
Low dead volume for improved resolution and molar mass distribution accuracy
Temperature controlled pumps for excellent flow rate precision regardless of changes in laboratory temperature
Dual flow RI (refractive index) detection for unmatched baseline stability

Time and solvent can be saved using the EcoSEC Elite GPC System with optional semi-micro columns due to the system’s low dead volume. The dead volume of the EcoSEC Elite GPC System (< 20 μL) is less than half the dead volume of conventional GPC systems.

UV Detector Option »

A variable wavelength UV detector is available as an optional component for the EcoSEC GPC System. One of the main applications of the UV detector is copolymer analysis.

The detector wavelength is variable from 195 to 350 nm 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 2 µL, while the shortest time constant is 0.5 seconds.

Calibration Standards

PStQuick polystyrene calibration standards contain pre-mixed quantities of polystyrene polymers in autosampler vials for the calibration of GPC columns. Addition of solvent is all that is required for easy preparation and analysis. 12 different kits containing polystyrene polymers of various molar masses are available. Of the 12 kits, 9 are individual kits, each containing 3 to 5 polystyrene polymers. The remaining 3 are composite kits containing 2 or 3 of the individual kits.

TSKgel GPC Columns

Tosoh introduced its first line of GPC columns in 1971. Ever since, Tosoh scientists have made important contributions to advances in polymer analysis by developing state-of-the-art GPC columns for the most demanding applications.

Semi-micro columns are the TSKgel columns of choice for use with the EcoSEC Elite GPC System. They are referred to as such since their dimensions are smaller than conventional columns in terms of internal diameter as well as in length: 4.6 mm or 6 mm ID × 15 cm vs. 7.8 mm ID × 30 cm.
