Automatic Intrinsic Viscosity Analysis of IVA Polymer Materials

Polymer Char has developed a reliable and fully automatic intrinsic viscosity analyzer for polymer materials IVA; dissolution temperature can reach 200 ℃. IVA R & D is built on a mature quality control platform, integrating a powerful dual-capillary viscosity detector and a very reliable high-temperature autosampler. At the same time, customers can also choose an infrared detector IR4.

The principle of the dual capillary viscometer is simple: the ratio of the pressure drop generated by the polymer solution through the stainless steel capillary line to the pressure drop generated by the pure solvent, and the pressure drop is measured simultaneously. The relative viscosity of the polymer solution is obtained from the pressure ratio, while the intrinsic viscosity is calculated taking into account the mass of the injected polymer.

Different from the capillary tube of Unova viscometer, IVA stainless steel tube capillary tube and pipeline do not need additional cleaning or flushing, can provide accurate viscosity value, and is durable. The subtle design of the heating elements and transfer lines ensures that the polymer is completely dissolved, even with high molecular weight polymers.

Can be used to analyze high molecular weight and ultra-high molecular weight polymers.
