The Viscotek TDAmax is a comprehensive and powerful advanced detector
Gel Permeation/Size Exclusion Chromatography system with temperature
control from ambient to 80°C. It is specifically designed for the characterization
of natural and synthetic polymers, copolymers, proteins, nanoparticles and
other macromolecules. As the world’s only fully integrated, advanced
detector system available from a single vendor, the TDAmax sets the
benchmark for GPC technology and is configured as follows:
- Integrated Triple Detector Array featuring a revolutionary Low Angle Light Scattering (LALS) Detector, four-capillary Differential Viscometer and Differential Refractive Index (RI) Detector.
- GPCmax™ Pump/Autosampler/Degasser Module for automated solvent and sample delivery.
- OmniSEC™ GPC/SEC software for complete system control.
The TDAmax 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 and creating an integrated Tetra Detector Array, the TDAmax will
also provide information on copolymer composition.
Triple and Tetra Detector Array
The Viscotek
Triple and
Tetra
Detector Arrays combine low angle
light scattering with viscometry and concentration for complete
and comprehensive macromolecular characterization. All detectors
reside within a temperature-controlled oven compartment (ambient
to 80°C) which also has space for 3-5 analytical GPC columns.
This arrangement minimizes inter-detector volumes to reduce
band-broadening effects and insures that detectors, inter-detector
tubing, columns and sample reside at the same temperature
throughout the course of the analysis.
GPCmax™
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 either the Triple or Tetra Detector Array 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 Triple and Tetra Detector
Arrays and GPCmax, along with data acquisition, processing and
export, and is 21 CFR part 11 compliant.
