EcoSEC Elite® GPC System

EcoSEC_Elite.jpg

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.

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.

 

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.
