Strict quality control of polymeric raw materials

Jul 11 2024

Testa Analytical reports how a German customer is using its GPC/SEC system to monitor the specifications of incoming raw materials.

Historically due to variability in the quality of its raw materials, the customer found that a percentage of their final product (aminoplastic resins) had to be discarded for not fulfilling the expected specifications. Working with Testa Analytical they have established strict QC routines on incoming materials using the GPC/SEC system.

Employing just a single refractive index detector, the GPC/SEC system has proven exceptionally reliable, running continuously with very little downtime. Because of the improved quality and consistency of their final product and vastly reduced waste the investment in the GPC/SEC system paid off very quickly.

Operating from room temperature up to 80°C, with high thermal stability, the Testa Analytical Differential Refractive Index (DRI) detector offers highly accurate and reliable determination of absolute concentration and total mass balance in GPC/SEC applications.
