Polymer characterization. (Hardware/Software).Cirrus Multi Detector software is said to provide a complete software solution for polymer characterization by multi detector GPC (1) A PC that uses the Linux-based gOS operating system. See gOS. (2) (GPC Group) Originally the Graphics Performance Characterization committee of the NCGA, the GPC Group is now part of Standard Performance Evaluation Corporation (SPEC) and oversees the following . Cirrus Multi Detector software is designed to acquire and analyze data from GPC systems fitted with any combination of refractive index A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two different materials, their refractive indices determine the angle of transmission , light scattering and viscosity detectors. The Cirrus package incorporates a 24 bit, high resolution, low noise data acquisition system, the PL DataStream, to interface with up to four user-selectable detector outputs. All operating conditions, raw data files, analysis methods, related calibrations and sample results are conveniently stored in Cirrus Workbook files for effective traceability or stored information, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the company. Cirrus Multi Detector analysis software permits fully interactive calculations of molecular weight, intrinsic viscosity Intrinsic viscosity  is a measure of a solute's contribution to the viscosity  of a solution. and radius of gyration Radius of gyrationA relation of the area or mass of a figure to its moment of inertia. If I is the moment of inertia about a line of a figure whose area is A, the figure's radius of gyration with respect to that line is. as a function of elution volume using a variety of data fitting options. Methods can be specified for GPC-viscosity, GPC-light scattering and triple detection calculation routines as required.
