The integration of a capillary viscometer provides an automated measurement of intrinsic viscosity of the whole sample and both amorphous and crystalline fractions.
The scanning capillary viscometer (SCV Rheolog[TM] by Rheovector, Exton, PA, USA) used in this study is able to quickly measure WBV at a wider range of shear rates.
The solution viscosity method requires relatively simple equipment--a glass capillary viscometer. However, expensive laboratory facilities and high level laboratory staff are required to facilitate the use of dangerous solvents.
The pressure-scanning capillary viscometer measures the viscosity of whole blood over a range of shear rates without the use of anticoagulants.[sup.16,19] It has been used in some countries, but not available in most clinical laboratories.
The instrument was a sealed gravitational capillary viscometer developed at NIST for volatile liquids.
The triple detector system features an integrated triple detector array (TDA) comprised of a low angle light scattering (LALS) detector, four capillary viscometer detectors, a GPCmax pump, autosampler and degasser module specifically designed for GPC/SEC applications.
In capillary viscometer measurements, the relative viscosity (dimensionless) is the ratio of the flow time for the solution (t) to the flow time for the solvent ([t.sub.0]),
To validate the results, the rheological properties of these materials were measured offline using a capillary viscometer. The online rheological measurement from the sheeting operation was in very good agreement with the offline capillary rheometry for the all-purpose, bread and durum flours.
