High Reliability
When the system is used with semi-micro SEC columns, featuring calibration curves with superior linearity*, and the standard polystyrene kit PStQuick, which ensures minimization of preparation errors, highly reliable data with minimized variation between systems may be obtained.
(*Compared with Tosoh's conventional products)
High Stability
The column oven has a double structure and a double temperature-control mechanism.
A double-path, double-flow refractive index detector (RI detector) is used for temperature control of the main units, including tubing. A stable baseline is obtained by suppressing fluctuation of the refractive index in the solvent.
High Reproducibility
The pumping unit features a newly designed structure and control system. Temperature control of the entire pumping unit gives high reproducibility which is not affected by varying solvent conditions or environmental temperature fluctuations.
Fast, Efficient, Low Solvent Consumption
Combined use with TSKgel semi-micro SEC columns (SuperMultiporeHZ, SuperHZ, SuperH, and SuperAW) allows fast, efficient separation and SEC analysis and reduces solvent consumption.
Easy Operation
Using the GPC Workstation EcoSEC-WS, the system can easily be operated through warm-up, analysis, and shut-down. The main unit may also be independently controlled using the operator panel.
The automatic purge function eliminates solvent replacement
and other time-consuming manual operations.
Global Standard
Compliant with China RoHS.
UL61010-1 and CE mark certification.
Also compliant with FDA 21 CFR PART 11*.
