RImaxTM Conventional Calibration System |
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.
