Multi Detector Software allows interactive calculations.

Press Release Summary:



Cirrus(TM) provides polymer characterization by multi detector GPC, and is used to acquire and analyze data from GPC systems fitted with any combination of refractive index, light scattering and viscosity detectors. Cirrus incorporates 24 bit, high resolution, low noise data acquisition system, PL DataStream, to interface with up to 4 user-selectable detector outputs. Software derives branching parameters from either Mark Houwink or conformation plots.



Original Press Release:


A Complete Software Solution for Polymer Charactarization by Multi Detector GPC


Polymer Laboratories has launched Cirrus(TM) Multi Detector Software, a package which provides a complete software solution for polymer characterization by multi detector GPC. Cirrus(TM) Multi Detector software is designed to acquire and analyse data from GPC systems fitted with any combination of refractive index, light scattering and viscosity detectors. The Cirrus(TM) 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'm Workbook files for effective traceability of stored information.

PL's Cirrus(TM) Multi Detector analysis software permits fully interactive calculations of molecular weight, intrinsic viscosity and radius of gyration 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. In all cases, Cirrus(TM) Multi Detector software derives branching parameters from either Mark Houwink or conformation plots.
