The Viscotek RImax is a robust Gel Permeation / Size Exclusion Chromatography system that is powerful yet easy to use. It represents the most reliable technology available for the
conventional characterization of natural and synthetic polymers, copolymers, proteins, nanoparticles and other macromolecules. The RImax is configured as follows:
- Model 3580 Refractive Index (RI) Detector with superior linearity and baseline stability.
- GPCmax™ Integrated Pump/Autosampler/Degasser Module for automated solvent and sample delivery.
- OmniSEC™ GPC/SEC software for data acquisition, processing and complete system control.
The Refractive Index (RI) Detector is known as the universal detector in GPC. It is used to measure sample concentration and determine dn/dc or refractive index increment. By adding a
UV/VIS Detector to the RImax, concentration can be determined for those samples having a UV chromaphore. When employed in tandem, the RI and UV responses can be ratioed to determine copolymer composition.
Refractive Index Detector
The Viscotek Model 3580 Differential
Refractive Index (RI) Detector sets the standard in GPC for the determination of sample concentration. It combines superior sensitivity and versatility with reliability, ease-of-use and excellent linearity over a wide range of concentrations. The Model 3580 mates seamlessly with the Viscotek
GPCmax and
OmniSEC software to form a complete Conventional GPC system. It can also be coupled with the
Model 3210 UV/VIS for copolymer compositional analysis.
GPCmaxTM
The
GPCmax is a unique, integrated pump, autosampler and degasser module specifically designed for GPC/SEC applications. It features a variable injection volume autosampler capable of handling 2 ml or 20 ml vials, an isocratic pump for pulseless and reproducible solvent flow and an in-line solvent degasser. The GPCmax is controlled by the
OmniSEC software and mates seamlessly with the
Model 3580 Refractive Index (RI) Detector to form a complete GPC/SEC system.
OmniSEC™ Software
OmniSEC is a powerful and flexible GPC/SEC software program specifically designed to maximize the information content and efficiency of the gel permeation chromatography (GPC) experiment. Key features include interactive programs for calculation of results in a real-time time environment, automatic baseline and peak detection, multiple peak analysis, copolymer and conjugate compositional analysis and determination of A2 and B22 values.
OmniSEC allows full control of the RImax GPC/SEC system along with data acquisition, processing and export, and is 21 CFR part 11 compliant.
