270maxTM Ambient Temperature System |
The Viscotek 270max is a modular advanced detector Gel Permeation /
Size Exclusion Chromatography system that operates at ambient
temperature. It is specifically designed for the characterization of natural
and synthetic polymers, copolymers, proteins, nanoparticles and other
macromolecules. The 270max is configured as follows:
- Model 270 Differential Viscometer/Low Angle Light Scattering (LALS)
Dual Detector.
- Model 3580 Refractive Index (RI) Detector with superior linearity and baseline stability.
- GPCmax™ Pump/Autosampler/Degasser Module for automated solvent and sample delivery.
- OmniSEC™ GPC/SEC software for complete system control.
The 270max will provide absolute molecular weight without extrapolation
or correction, molecular size (Rh to less than 1 nm and Rg), and
intrinsic viscosity as well as information on structure, conformation,
aggregation and
branching in a single GPC/SEC experiment. By adding a
UV/VIS Detector to create a modular tetra detector system, the 270max
will also provide information on copolymer composition.
 Model 270 Dual Detector
The Model 270 Dual Detector features a proven four-capillary
differential viscometer and revolutionary Low Angle Light
Scattering (LALS) detector that operate at ambient temperature.
The viscometer measures intrinsic viscosity and is used to
determine molecular size (Rh to less than 1nm) and density. The
viscometer also provides additional information on structure,
conformation, aggregation and
branching. The LALS detector
provides absolute molecular weight without the assumptions,
corrections or extrapolations required by alternative light
scattering techniques such as MALS.
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 270 Dual Detector and 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 multiple detector chromatography 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 270max GPC/SEC system
along with data acquisition, processing and export, and is 21
CFR part 11 compliant.
