    High-performance polymer screening reveals structural nuance

    A major European polymer producer has turned to Testa Analytical’s COMBO-ONE detector to uncover subtle but significant structural variations in its range of high-performance water-soluble polymers.

    Although the polymers in question share similar molecular weights and distributions, their differing architectures have a major impact on performance in industrial applications. By integrating the COMBO-ONE into a GPC/SEC setup, the manufacturer has been able to distinguish these variations with high precision - something not easily achievable with conventional techniques.

    Testa Analytical’s Hizkia Chandra explained:

    “From the very first run, the Combo ONE provided meaningful data. When linked to a Shimadzu GPC/SEC system, the unit immediately highlighted structural disparities between samples that previously appeared identical.”

    The COMBO-ONE combines refractive index and viscosity measurements in a single, delay-volume-free device. This compact, dual-function detector simplifies system setup while delivering unmatched accuracy in assessing polymer composition. It’s an ideal tool for any lab needing to go beyond molecular weight to understand the full structural profile of a polymer.
