How to Operate BeSEC for Molecular Weight Measurements

When it comes to absolute molecular weight measurement, accuracy isn’t optional — it’s the baseline. That’s exactly where BeSEC steps in.

In our latest BeSEC operation video, we walk you through the complete workflow for precise molecular weight analysis — from standard sample preparation in THF to automated injection, real-time system monitoring, data acquisition, instrument constant calibration, molecular weight calculation, and final report generation.

Powered by dual-angle light scattering, BeSEC enables reliable measurement of the absolute molecular weight of proteins, synthetic polymers, and natural polymers, while also revealing molecular size through the radius of gyration (Rg) — all with an intuitive, user-friendly operation experience.
