In previous applications, we have discussed how to measure Intrinsic Viscosity with m-VROC® and microVISC™. Intrinsic Viscosity can be used as a means to establish molecular size, structure and conformation of solute molecules in a given environment. In order to make intrinsic viscosity measurements faster and easier, the number of viscosity measurements can be reduced to a single concentration. In this study we present a comparison of Single-point and Multi-point Intrinsic viscosity methods for a number of polymers and bio-polymers.
Our results show how, thanks to the superior repeatability of VROC® powered systems, both Single-point and Multi-point intrinsic viscosity measurements present good correlation. This allows Intrinsic Viscosity to be used as a fast and easy Q&C indicator with impresive sensitivity to molecular interaction. Remember Intrinsic Viscosity opens the door to the characterization of:
Check out our Intrinsic Viscosity application note with m-VROC™, the most versatile viscometer in the market offering:
In Octover 2015 RheoSense presents VROC® initium. The first fully automated high throughput viscometer/rheometer. VROC® initium allows for the viscosity fingerprint characterization of up to 96 samples. Unattended! Its automatic capabilities are meant to revolutionize intrinsic viscosity measurements allowing for extensive characterization of molecular conformation changes as a function of pH, temperature...
