Applications |
 Viscotek specializes in solution techniques for macromolecular characterization. Our technologies are employed in academic, industrial, biopharmaceutical and government
accounts throughout the world in a tremendously broad range of applications including natural polymers such as polysaccharides and cellulosics; synthetic polymers such as adhesives, epoxies and plastics; and biopolymers such as proteins and protein conjugates.
Our application Notes describe the characterization of natural and synthetic polymers and biopolymers by Gel Permeation Chromatography (GPC), Flow Injection Polymer Analysis (FIPA) and Dilute Solution Viscosity (DSV).
- GPC/SEC application notes explain the use of concentration, viscometer and light scattering detectors to obtain a distribution of absolute molecular weight, size and intrinsic viscosity, as well as information on conformation, aggregation, branching and copolymer composition.
- Flow Injection Polymer Analysis (FIPA) application notes describe how advanced detector technology is employed in the QA/QC and Process control laboratory to obtain a fast, accurate and precise molecular weight, size and intrinsic viscosity in 3-5 minutes without the need for elaborate sample preparation.
- Dilute Solution Viscosity (DSV) application notes explain the use and advantages of the Viscotek Relative Viscometer as a preferred alternative to glass capillary tubes for the determination of relative, intrinsic, inherent, reduced and absolute viscosities of dilute polymer and protein solutions.
- Dynamic Light Scattering (DLS) application notes illustrate the advantages of our patented Single Mode Fiber (SMF) optic technology for the characterization of macromolecules and biomacromolecules. Dynamic Light Scattering is a fast, easy and accurate way to measure molecular size and screen for aggregation, and SMF technology provides superior sensitivity, allowing you to work with smaller sample volumes and lower concentrations.
We have also included Technical Notes that explain various aspects of detector operation and theory, including the revolutionary, patent-pending Low Angle Light Scattering (LALS) Detector, as well as an extensive Bibliography that provides a listing of articles and papers describing the use of Viscotek instruments, systems and software in the academic, biopharmaceutical and industrial markets.
Application Notes and Technical Notes are all available in a pdf format which can be downloaded directly from the website. If you have an application question or issue which is not addressed in the Application Notes, Technical Notes or
Bibliography, or simply can’t find the appropriate reference, please do not hesitate to contact us at info@viscotek.com.
